Dear All,
I am trying to analyse one Rectangular steel tank (water) having size approx. L X W X H = 8 x 1.5 x 2.2 m. I modelled it in STAAD Pro and applied loads as below:
1. Side walls hydrostatic pressure triangular
2. Base uniform pressure with intensity H x water density.
The tank will...
Dear All,
I am designing a foot over bridge crossing the road (State Highway) and all connections are bolted connections. I am having a doubt about the selection of bolt. Shall I go with 8.8 Grade bolt or HSFG bolt. Is there will be too much Vibration due to pedestrian movement in bridge? I...
Dear All,
I am having a doubt about bolt torque.
I am designing a steel structure in that I have M-24 (24 mm diameter) bolt 8.8 grade with maximum tension of 125 kN. Is it mandatory to calculate torque for this case or simply I can follow the Standard torque chart available? Is torque value...

Dear All,
I am having doubt about consideration of direction factor in wind load calculation by BS6399-2. Please check the attached steps and let me know about considerations.
Like this I need to calculate for every direction ? means N,S,E,W?
Dear All,
I am designing s Space frame which is having an oval shape opening, due to opening space frame is behaving like cantilever. That's why to provide good stability we provided cantilever truss from columns as shown below. The space frame is supported on truss as shown below. Here steel...
Dear All,
Is it possible to make roller Support carrying bending moment? If some one is having real life example please share. And please share the design considerations also.
Dear All,
I need to refer for canopy wind pressure calculations- COOK, N.J. The designer’s guide to wind loading of building structures. Part 2: Static structures London: Butterworth Scientific, 1985.
If some one is having softcopy or link please share.
Dear All,
I am designing a space frame which is supported on steel columns. there is a central architectural feature as well. when I am modelling all structure in one model and running seismic analysis, then central architectural feature is taking to much load and members are failing (due to...
Dear All,
I am designing a truss to column connection. I need your comments about connection. Two options of connection has shown below. which one will be the structurally sound.
Connection-A
Connection-B
In connection A there is eccentricity but I can connect both bracing and bottom...
Dear All,
