Bearing Capacity

Recommended Posts

I have not seen such a limit written anywhere. However, the lowest value of bearing capacity (BC) for the building sites I have come across during my professional practice, was mostly 0.5 tons per square foot (TSF).

In only one case, the reported BC was 0.25 TSF. However, the client was advised to change the site, as such a low BC indicates a very weak soil, ordinarily requiring a very heavy & expensive footing design.

As such, IMO 0.5 TSF may be considered a reasonable lower limit of BC for a building site.

Regards.

Does code recommends any minimum limit for bearing capacity if the bearing capacity of actual soil is known?

Known or unknow?

      This article is intended to cover design of piles using Ultimate Limit State (ULS) method. The use of ULS method is fairly new for geotechnical design (last decade). The method is being used in multiple countries now (Canada, Australia etc). The following items shall be discussed:

      Overview


      Geotechnical Design of Piles (Compression Loads, Tension Loads and Lateral Loads)


      Structural Design of Piles (Covering both Concrete and Steel)


      Connection of Pile with the foundation (Covering both Concrete and Steel)


      Pile Group Settlement


      Things to consider



       

      1. Overview

      Piles provide a suitable load path to transfer super-structure loads to foundation where shallow foundation are not suitable - this can be due to a number of reasons like existing space constraints or suitable soil strata is not present immediately below structure. Other uses can be to meet design requirements like to have reduced settlement etc.

      This article shall cover the use of straight shaft cast-in-place concrete piles and straight shaft driven steel pipe piles. There are a number of additional piles types like belled concrete piles, precast concrete piles, screw / helical steel piles etc but the discussion to choose a suitable pile type is not in the intended scope of this article. The article is intended  to discuss design requirements for straight shaft piles only (both concrete and steel) . The aforementioned topic about pile selection is a very diverse subject and requires a separate discussion on its own.

    • Material behavior can be idealized as consisting of an 'elastic' domain and a 'plastic' domain. For almost 200 years, structural design has been
      based on an elastic theory which assumes that structures display a linear response throughout their loading history, ignoring the post-yielding
      stage of behavior. Current design practice for reinforced concrete structures is a curious blend of elastic analysis to compute forces and moments, plasticity theory to proportion cross-sections for the moment and axial, load, and empirical mumbo-jumbo to proportion members for shear.

    • AoA all,

      Is it mandatory to do column concreting upto the soffit of the beam in a single pour ?

      What code says about the construction/cold joint location in column ?

      Majority of the contractors are pouring the column concrete upto the soffit of the beam (full height of the column), some contractors leave the column height about 9" to 12" below the beam level and then fill this 9" to 12" column height with the beams & slab concreting. On one site column concreting was stopped at the mid height and the remaining half was filled on the next day.

      Thanks

    • Please clarify the following confusions one by one:-

       

      1. If we run P-delta analysis in ETABS, then should we ignore stiffness property modifiers for beams and columns? I have heard that if we perform P-delta analysis and apply stiffness modifiers at the same time then the moment magnification process is doubled...?

       

      2. ETABS considers selenderness of a column by applying moment magnification factors. If we run P-delta analysis also, does it mean that the selenderness of column is being over-estimated? I mean once the moments are magnified in P-delta analysis process and again through moment magnification process?

       

      Please help me understand the software myth and clarify above confusions.

    • Assalam o alaikum.
      According to ACI 12.5.2,
      development length for fc' = 3000, fy=60000, for normal weight concrete and epoxy less reinforcement, The required development length comes out to be
      for #3 = 8.2 inch
      for #4 = 10.95 inch
      for #6 = 16.42 inch
      for #8 = 21.9 inch
       
      And if in my case, ACI 12.5.3 is not fulfilled, it means now i have to provide ldh as mentioned above. ldh is STRAIGHT EMBEDMENT LENGTH + RADIUS OF BEND + ONE BAR DIAMETER as shown in figure attached. Now my question is, if in my case, main reinforcement of beam is of #6 and #4, minimum column size required will be 18 inch and 12 inch respectively. Lets say by any means, i can not select #4, #3 bars and size of column where bars are to be terminated is 12 inch, how to fullfil this development length???

    • Dear all,

      I am trying to design shearwalls through ETABS with temperature load applied over shell. At various location, spandral section fails in Shear due to temperature and piers (sometime in shear, mostly in flexure).  (See Attached Image)

      Certainly all the problem in Shearwalls are due to temperature. I don't want to increase cross section of spandral or pier at some location just due to temperature load case as it will appears non-uniform with rest of the wall. 

      I have seen stiffness modifier affect distribution of forces and also rigid/semi rigid daiphragm assumption. 

       

      Can anybody guide how to properly design the shear wall with temperature load applied in ETABS or share any similar experience. Thanks in Advance.

      Hi all, I am designing the foundations of a small double storey building in Karachi for which no geotechnical investigation is envisaged. Can anyone tell me whats the average allowable bearing capacity in Karachi. Normally in Lahore, it ranges from 0.5tsf to 1.25 tsf. I would be glad if anyone can tell on basis of his experience in Karachi.
      Thanks

      Assalam-o-alaikum,
       
      For calculating required area of a column footing, we normally use 'Dead+Live' load combination, for locations having no or very small snow loads comparable with live load. However, there are several  hilly areas in Pakistan ( like Murree,  and Gilgit etc), where the snow load is not only much higher than the live load (especially for single storey structures), but may also sustain on the roof for many days.
       
      My question (with reference to ACI 318-08 and ASCE 7-05 codes) is: What load combination we should use to determine required area of column footings, for these high snow fall areas? Whether 'Dead+Live', 'Dead+Snow' or some other?
       
      Would appreciate your opinion and comments, supported by relevant references, if possible.
       
      Thanks.

      Aoa.
       
      While designing foundations for building and other structures, allowable bearing capacity is used to calculate required area (spread) of footing. There are two approaches of structural engineers, regarding value of allowable bearing capacity, actually to be used.
       
      First approach says that the weights of soil below ground level and the footing concrete must be deducted from the allowable bearing capacity value given in the soil investigation report, to determine net bearing capacity. This net bearing capacity is to be used to be used for calculating footing area required to support the load from superstructure.
       
      The second approach, says that NO deduction is required for soil and concrete below ground level, because:
      a.   soil investigation is carried out while original soil over burden is in place, and only superstructure load is to be carried out by the foundation,
      b.   Allowable bearing capacity given in the soil investigation report is very conservative, as it is commonly calculated by employing a factor of safety of 2.5 to 3.
       
      The first approach results in comparatively larger footing sizes.
       
      The question is, which of the above two approaches should be followed? And, why (code or some other references)?

    • @ali7988 hameed.. I think you want to apply partition wall load on floor slab, for this purpose you can simply draw a null/negligible frame element and apply load over it.
    • Sorry, I m not sure what you meant. You don't need to include a member in the model just to add its load. You need to model only those members that are essential for completing the load path (structural members).
    • Looking at the figure, one cannot figure out the complete load path for a particular loading scenario. So, it is not possible to give a specific advice. But, the way these pipes are connected, there be moment due to the eccentricity of connections in addition to axial forces. In addition to axial and flexural stress, shear stresses can also dictate the thickness required for the pipe, if the load path includes these forces.
    • Assalamualaikum,  Im designing a connection a pipe to pipe, between this pipe i have to add a plate to connect the pipe with welds. How can i determine the thickness of the pipe? Do i just design it based on tension load on the pipe? Cause my senior said that theres an eccentricity and i have to design it to resist such loads, but im not sure. Heres the figure of the drawing. Regards Groszni
    • do you calculate the dimension of the stiffner as a tension member by using these load-> required load for stiffener = force load by beam flage - column web resistance ?
    • Please see these topics: http://www.eng-tips.com/viewthread.cfm?qid=347923 http://www.eng-tips.com/viewthread.cfm?qid=1734 Thanks.
    • W/s Imran, It is very hard to say if your FYP would help you in securing a job but one thing that is for sure, is that you will get skills like assessing an existing structure, doing base isolation and information about seismic codes and the response of a building to a seismic event - such skills would help you wherever you go. I am not aware of use of base isolators in Pakistan, there might be sensitive military installations where these are being used but I don't know if the market is really big for that and there is immediate need for people having that experience. But like I said above, you will get a skillset that any structural firm in Pakistan would value provided you do your project correct and develop understanding of what you are doing. Thanks.    
    • Can I model the load of partion load(brick wall load) by modeling a beam with very small dimensions such as 1 cm * cm
    • @UmarMakhzumi.. @Ayesha...Thank You for your concern. Yes we r on the same page . However my interest was only to highlight the fact that pile cap design is not like slab, due to pile spacing criteria and typical patterns, it will behave like a deep beam in almost every structure. However i feel there is no proper technical inputs on this component of structure and engineers follows whatever practices are in their offices. In this regard i would like to add little knowledge as per my experience , that unlike the normal slab, the critical sections for maximum FORCES will also be changed , it needs 5 to 6 special investigation as per the reference handbook mentioned in commentary of ACI.  Regards  
    • @ZOHAIB SATTAR NAGRA..  Applying temperature to vertical elements (Wall) will hardly effect your design, this is my observation.      "It is pertinent to mention that biggest trouble for frames/walls will arise due to the application of temperature loading on slab area".
