someone can guide me with code reference, what should be drifting limit for this kind of open parking shed ?? roof cladding is steel sheet.

Thank you for your feedback. But when i should apply minimum value? when windward and leeward sum is less then 16 or if any of the value (windward or leeward) less then 16 i should change that value with minimum load ?

As per ASCE 7-10 , 28.4.4 minimum wind load should not be less then 16 psf for walls , so what is this mean ? I am using MWFRS envolpe method and my structure is closed structure .One of my friend told me that if sum of my windward and leeward value comes less than 16 psf than i have to apply 16...

I am designing a 2 storey small light gauge steel beauty salon (total area each floor 64m2), but i am confused in live load what should i consider live load for first floor. First floor containing makeup area zone , facial persnol care, manicure area etc.

i am designing a steel portal frame for industrial shed , which is 36 meter in clear span , as per IBC code allowable vertical roof deflection limit is L/120 (not supporting ceiling ) against Dead + Live Load and L/180 against live load which means allowable deflection for my portal frame is 300...

@ Aesur , thank you for your explanation in detail. you are correct main frame rafter is carrying only uplift wind force but roof purlins carrying uplift and downward forces both. currently I am considering that the solar panels are directly screwing on the roof sheet with the same roof slope...

I am desiging a pre engineered building which is 44m in width , 120m in length and 8.5m eave height (Metal roof slope is 4 degree). I made the calculations for wind forces by using the code ASCE 7-05 in result all the wind load forces are upward (suction) on roof steel rafters , but now client...

@KootK. Fitness gym with weights.

Unfortunately, for some reason i can't go with concrete option.

Client wants the gym on first floor of 2 storey steel building (semi equipped gym). Gym size is 12mx18m. Main frame structure is consist of hot rolled columns and beams and peimary member of floor is cold form steel joist (back to back Cee sections) @ spacing of 300mm center to center and as a...

Yes boundary wall mean property line or you can say compound wall. Yes light weight concrete planks will be placed horizontally.

i am using H shape steel column as post of boundary wall and using inside post to post light weight concrete planks. Any one can tell me allowable deflection limit of H shape steel post against wind force??, and any code reffrence??

Any one can tell me what DB level we can achive if we use 90mm C section steel wall with both side single layer of 16mm gypsum board. Any code reffrence ?

I am designing an isolated footing of a steel column on SAFE , the bearing pressure value is 67kpa and 90 kpa on service load and factored load respectively with 5mm and 8mm settelment similarly. And soil investigation report says that the net allowable bearing capacity is 70 kpa based on...

@derim01. Your observation is correct this project is based in UAE and yes 1.5m deep block work is consultant requirement. I designed the beam as a grade beam as it is resting on the block wall and i assumed that all the vertical load will transfer to the soil through block work below and no...

@oldestguy Below wall is for holding the soil under the salb and this grade beam/plinth beam is also acting like a tie beam as it is connected from both side with pedestal of isolated footing. I think the above wall selfweight will transfer to the footing column through grade beam/plinth beam ...

I am designing a grade beam which is connected with the isolated footing pedestal both side, furthermore the grade beam is carrying the self-weight of block wall so I have few confusion as mentioned below can someone please suggest in this regards. 1: grade beam is carrying the self-weight of...

i am designing a single storey light gauge steel structure with aerated concrete infill (650kg/m3) in walls and both sides of the wall is cement board permanent shuttering, so i have one doubt that if the structure is single storey do i need to take self weight of aerated concrete while...

Site welding is difficult due to some reason. I am also intrested in option 1 but only issue in this connection is top bolt head,  these bolts head will creat problem at site for fixing the floor decking sheet. Any one can suggest how i can fix decking if i choose option 1?? Floor Decking is...

I have a 1.5m overhang with concrete and decking sheet. Main beams and secondary are on same level so moment connection needs to made between the main and secondary beam (Cantilever Structure.jpg). I have two options for connection. 1. Fin plate in between and flat plate on top and bottom (Con...
