@sameersaleem how to check which punching perimeter safe is using? @umarmakhzumi you mean to say provide raft footing under 4 columns so the water tank load should be equally divided on these 4 columns?

Load on top right column at service = 118 kips Load on bottom right column at service = 60 kips The option of moving water tank can be considered. Yes there is a wall between two columns at ground level. There is no wall footing etc.

Asalamualaikum all, I have columns which are conflicting with the underground water tank as shown in figure. So I have decided to make underground water tank base slab as a footing for column. So I import etabs model to safe and just take uniform water load on base slab and point load from columns. This is the residential house. The BC is 2tsf. But SAFE is showing tension on the base slab and the thickness from punching is 30''. I believe that thickness is too high. What can be the error? Is this approach is correct for design base slab of ugwt to carry load of two edge columns?

For Weak Storey check If columns are flexure controlled, the shear strength is the shear corresponding to the flexural strength. (Ref: http://www.iitk.ac.in/nicee/IITK-GSDMA/EQ06.pdf) So I used to calculate flexure strength (Flexural capacity) of column section and then divide this by the length of column to find the maximum shear it can resist before flexure failure may occur. This will give me the shear strength of an individual column. then adding these all will give storey shear strength. its like adding moment at top and bottom of the column to get the shear force of the column. (the way usually people do to calculate internal forces manually) I dont have exact reference, but i will research on it and will let you know.

To find weak storey, I used to calculate flexure capacity of columns and then divide them with member length to get shear strength of the column. Then I add all the columns shear strength present in one storey to get the shear strength of one storey. Is this method correct?

Thank you all

For grillage system, is there any special detailing requirement?

Asalamualaikum everyone, If I have two beams of same stiffness and present at same level, how can i decide which beam is supporting the other beam? What would be moment diagram look like? How to do the detailing at the mid joint? What change should be done in ETABs or SAP software? Attached is the figure of the model I have break one beam so the other beam should act as support but moment diagram show only positive moment for both beams. Thankyou

Being a civil engineer, we learn how to design RC structures which consists of beams and columns. what about load bearing structure? Where can I get information regarding design of brick masonry structure that is common practice in most part of Punjab... And can we model it on Etabbs and check pier and spandrel forces, etc?

Pre-Engineered Steel Buildings..

Well I have found the relevant document. Following is the link for the required document: https://de.usembassy.gov/wp-content/uploads/sites/21/2016/08/Attachment-J.2-2015_OBO_Building_Code1.pdf

the figures in the above post are not opening. Can anyone please share the values of SDS and SD1 for Lahore. Only 2 figures shared by @UmarMakhzumi are opening which have values for Karachi and Peshawar only

@Rana thanks but I got the estimate

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

What is the difference in cold formed steel structure and Light gauge steel structure?

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

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.

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..

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.

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

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.

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

Wa alaikum us salam, You can use sciencedirect, academia and researchgate for research papers.

Thank you for explaining

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.
