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...
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...
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...
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...
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...
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...
I am designing a slab on grade foundation for G+3 hospital building, loads are coming on slab foundation through LGS walls and steel columns (UDL loads and Point Loads).
Plot is 1.5m deep from adjacent road level so we have plan to fill that plot with special granular material up to road level...
I am designing a double story amphitheater and clear span of this structure is 20m ,so i am stuck in floor beam design , either it should be a simple I beam(Standard Sections) or i should go with hot rolled truss beam so any one can suggest for this type of clear span (20m) which option will be...
Hello Everyone!!
I am designing a slab on grade for warehouse (sizes 10mx20mx6m) , which carries the load from steel column at the edge of slab , but the issue is that , a 250mm deep trench is running for electrical cabling along the steel column throughout in 250mm thick RCC slab so below is my...
Any one can tell me how i can calculate soil bearing capacity at 2m level from below provided data however in soil test report soil bearing capacity is recommended 0.75kg/cm^2 at 1m depth for shallow foundations but i want to construct my footing below the underground water table level at 2m...

I am designing a shallow foundation for a G+3 hospital structures, according to soil investigation report the bearing capacity of soil at depth of 1m is 0.75 kg/cm2 (medium stiff clay type) and at depth of 2m the bearing capacity is 1.55 kg/cm2 (medium dense soil)but the problem is that the...
Any one can tell me any thumb rule to find the approximate increment value in bearing capacity of soil (for initial design) after proper compaction and adding the selected granular material???
For example existing soil bearing capacity is 50 KN/m2 if we do compaction in proper way and add 30...
