Asalam-o-alikum wr wb everyone! I am very excited to announce the launch of "Structural Engineering Forum of Pakistan". Its a open discussion forum directed to Civil/Structural Engineers. The purpose is to have discussions, to shun ambiguity and to overall uplift the structural design practice. I welcome everyone aboard. I hope this forum meets serves its purpose, May Almighty ALLAH bless you all. Warm Regards, Makhzumi!

Hi everyone, My name is shabaz bangish. I am student of civil engineering at NUST. I am from Karachi, Pakistan.4 Its a very good initiative and I believe there would be a lot to learn here. see ya around guys!

Wind Tunnel Loading Data Wind Tunnel Loading Data Wind tunnel data is huge and tedious to input in ETABS or structural softwares. This data is produced from the wind engineering team’s softwares and usually provided in excel format. Usually if the building not regular, number of load cases are more than 20. How to import all that data into ETABS model is still a big issue because ETABS only lets you export the data to excel. There is no import facility from any database or excel sheet. Unlike SAFE and SAP, ETABS does not offer the facility to use interactive database editing. Well, I encountered this problem in my recent project, and then atlast I was able to import this bulk of numbers successfully in ETABS by using excel and VBA. Although I wrote the code for the format of data presented to me by the wind engineering team but it can be quite easily modified to satisfy other formats. Alternatively the wind tunnel data can be reformatted to match with the format, the coding accepts. If someone out of you has faced a similar problem and is unable to execute it, you can contact me personally. May be I upload the sheet soon here but for sure not now.

Hi, I have been assigned to derive the unit load method formula ∆ =∫(Mm/EI)dx ....so if anyone could give me link of proper derivation of this formula or attach scanned pages or soft copy of pages,I will be grateful.BTW I need it before tomorrow.Tomorrow is deadline of submission. REGARDS,

when we have raft foundation, is it necessary to draw it as we draw slab or just select all the joints at base level and turning them to fixed support will generate the effect of raft in analysis?

Hi I have uploaded a checklist for ETABS which i prepared a year ago! Thought to share! Will make it part of my next publication too! http://www.4shared.com/office/ITulouWj/Checklist_ETABS.html

no need to draw the raft in ETABS unless you are doing analysis of a very heavy building where soil interaction effects are critical....even for that its done by springs....

you need to make them fixed or pinned...and then export to SAFE and draw there the raft and do analysis in SAFE

I am Ali Ahmed, working as lecturer in University of Engineering & Technology, Lahore. I have completed my MSc Structural Engineering from the same university. I was the topper of my BSc Session (2004) & won four gold medals. Along with the lecturer-ship I am also participating actively in different research projects being carried out in UET Lahore.

Well check the tutorials section, i have posted my tutorials there for ETABS. You can download a very simple book i have written there but its not about tutorial its about using ETABS. I will soon upload the solved examples in ETABS too..the best thing is solve an example manually and then ur self try to get the same results (or similar of course) from ETABS! and see why not u getting the same results. This way you will better explore the options and menus.
