  1. Cost per square feet

    Asalamualaikum Anyone know cost per square feet for stone buildings (the one in northern areas), concrete structures, steel structures and block masonry structures in Pakistan? A rough estimate.. Thankyou
  2. Cold Formed Steel Design

    What is the difference in cold formed steel structure and Light gauge steel structure?
  3. Asalamualaikum, Are seismic zones same for eurocode and UBC? In UBC, we have zone 4 as the high seismic zone. In Eurocode, do we have same seismic zones? I am doing risk assesment using ELER software, it have three seismic zones for European building, Zone 1,2 and 3... What is the PGA for Zone 1 2 and 3 for European building codes? I am attaching a picture found from the following website http://www.protezionecivile.gov.it/jcms/en/classificazione.wp stating that Zone 1 is most dangerous zone Thank you for the help
  4. Pushover of INFILLED RC FRAME

    You can not design infill walls since they are unreinforced masonry. You can do analysis by considering infill as an equivalent single strut means considering it as a truss element by providing moment releases in the RC frame.
  5. Seismic dynamics

    This is related to calculus... you can study the theory about complex numbers... refer calculus by howard anton For seismic dynamics refer Structural Dynamics by Anil K Chopra..
  6. Shear capacity of Column

    Thank you all. I was thinking whether ties contribute in shear the same way as they do in beams when called as stirrups? I have read somewhere that ties do not contribute in resisting shear. They are used to prevent main bars in columns from buckling.
  7. Shear capacity of Column

    Asalamualaikum, If I know any column section, I can compute its section capacity in terms of yield moment using SAP section analysis or Response 2000 softwares. But if I want to find whether a column is failing in shear or not, what procedure should I use? For example, I have a column of 6'' x 18'' with 6 #4 bars and ties of #3@6'' c/c. I have done pushover analysis on software, Now I want to check whether column is safe in shear or not. So I note down the internal shear forces of column from the software at each step of pushover analysis and manually compare them with column shear capacity using ; Column shear capacity = Shear force resistance due to concrete (2 * lamda* fc'^1/2 * bd) Is this the correct method? or do I need to consider ties as well in resisting shear? If yes, then Vs=Avfyd/s formula will be used for ties resistance or something else? Thanks for the help
  8. Dear Fellow Researchers, Academicians, and research students, NED University of Engineering & Technology in collaboration with Institution of Engineers Pakistan (IEP) is organizing 9th International Civil Engineering Conference (ICEC 2017) on December 22-23, 2017 at Karachi, Pakistan. The congress details are available at its website www.neduet.edu.pk/icec Also attached is congress flyer for information and dissemination among your peers. Abstracts submission deadline has been extended till October 31, 2017. International Civil Engineering Conference (ICEC) is a regular feature in the calendar of events for Institution of engineering Pakistan and its Organizing partner NED University of Engineering and Technology Karachi. It is being organized frequently for almost two decades now. Eight international conferences have been organized in the past. Every year, the ICEC is held under an innovative theme related to contemporary issues that relate Civil Engineering and Socioeconomics of the society. The latest version of ICEC was held on December 23-24, 2016 at Karachi. The conference was organized in collaboration with Federation of Engineering Institutions of Islamic Countries (FEIIC), Federation of Engineering Institutions of South and Central Asia (FEISCA) and The Asian Civil Engineering Coordinating Council (ACECC). Theme of this congress was “Ensuring technological advancement through innovation based knowledge corridor” More than 40 international papers were presented at the 2016 conference including those from United States, United Kingdom, Malaysia, Srilanka, Bangladesh, Iran, and Nepal. The event was attended by a number of delegates both from academia and industry that provided a great opportunity for the stakeholders to meet and discuss various issues related to Civil Engineering education, profession and recent advancements. This year, the 9th International Civil Engineering Conference (ICEC 2017) will be organized on December 22-23, 2017, under the theme “Striving towards Resilient Built Environment?” The idea is to bring together latest civil engineering knowledge, research and development efforts from scientific community, engineers and practitioners that can help in contributing towards enhancing the resilience of the societies and thus establish a better built environment. The conference proceedings are published through blind peer-review procedure. The confetence will cover all areas of civil engineering, including, but not limited to, the following: · Structural Engineering · Construction Project Management · Earthquake Engineering & Design · Transportation Planning · Traffic Simulation and Modeling · Disaster Management · Geotechnical Engineering · Water Resources · Environmental Engineering For further details, contact the undersigned. Best Regards, ------------------------------------------- Dr. Farrukh Arif Co-Convener, ICEC 2017 Assistant Professor, Department of Civil Engineering, NED University of Engineering & Technology, Karachi, Pakistan farrukharif@gmail.com
  9. Structural Analysis and Design Research Papers

    Wa alaikum us salam, You can use sciencedirect, academia and researchgate for research papers.
  10. Simply supported stairs with large slab thickness

    Thank you for explaining
  11. Simply supported stairs with large slab thickness

    Flight#3 is designed as simply supported, it is resting on centre of landing at elev 6'6" and centre of landing at elev 11'6". This has reduced the length (L), so the waist slab thickness is reduced from 11'' to 8''. Personally, I don't know whether it is a correct practice to support a flight on landing rather than beam and consider it as simply supported. Thank you.
  12. R/f at top in isolated footing

    Asalamualaikum Why some engineers put reinforcement in top and bottom? They used to put same bars in top and bottom of footing.. What can be the reason?
  13. Asalamualaikum I am designing ground+1 240sq yard residential bungalow.. Stair plan is attached.. If i take flight#3 (marked as f3) as simply supported then thickness comes out to be 11"... so do we provide that much thickness for waist slab?? or should i make flight#3 to rest on landing at elev 6'6" and elev 11'6" and adding point load on flight#2 to reduce slab thickness?? Thankyou
  14. Strap Footing

    Thank you for sharing the sheet and relevant material
  15. Strap Footing

    Any sheet/pdf for design of concentric and edge footing tied with strap beam?
