Hi Dear,
I am working on a new project that requires reinforced concrete walls as shear wall. Due to space constraints, I cannot increase the thickness of the walls.
Currently the walls are failing in shear. it's an underground structure with extreme ground shock loads.
The PMM ratio of wall...
Hi Guys,
I want to learn how to design shallow buried shelter.
the shelter shall be protected against chemical, biological, radiological, Nuclear & explosives.
Is there a good handbook/guide/book with examples for such kind of structures.
I am particularly interested in the effect of earth...
hey guys,
As you know, laying out trusses for a complex roof is a pain.
I know there are some software that are capable to generate truss layouts such as truss4 & AGACAD etc, but almost all are paid.
Is there any free software for the same work?
Hello Structural Engineers,
I am working on the retrofit of column & Footing.
The current load capacity of column is 1900 Kips (24" x 36" with 14-dia 1" bars) & an increase of 500 kip is required.
A jacket thickness of 6" is required at all sides.
I just don't know how to calculate the Shear...
Hi Fellow Engineers,
I was designing a raft for a mid rise 17 story residential tower, It was in my knowledge that Modelling Stiff element under column decreases the max moment because of decrease in clear span.
Even CSI knowledge base acknowledge that modelling of stiff element is a non...
Dear Engineers,
I am designing an elevated water supply tank (90 feet above ground) of 200,000 gallons, Should I take weight of the water in the seismic weight of the structure for calculation of base shear.
Most Codes define fluid loads separately, meaning they are neither placed in live nor...
Hello Everyone,
I ran in to a problem defining design strips for Raft foundation perpendicular to shear wall, usually i provide column strip at L/4 on either side of the column. Is it the same for the Shear Wall?
will this shear wall act as a Hollow rectangular section?
I have attached an...
Dear All,
Hope you are doing well,
I am working on a rehabilitation of fire damaged structure, New steel beam (W section) is provided between two existing concrete beams to reduce span of existing concrete slab, I cant add Lateral bracing, can I reduce the unbraced length by bolting Top flange...
