How to check the section (bracket fixed as shown below) for torsion ?? any general formula for min thickness??

Temperature change (range ) specified in project spec as 56 degree Celsius. They dint provide any other temperature data like( Ambient temperature , Max and Min temperature) Is this data sufficient for the temperature load calculation in staad pro ?? Any American code reference for temperature...

Hi guys, Please help me to find a solution. I'm using Staad V8i for strcural design. I wants to model hanger wire 3mm( Dia)Thk in staad.

Two beams with different sectional properties ( see the attached file. Fig 1 & fig 2 ) supported as simply supported at same span and same loading. While analyzing the section shown in fig 1 deflect more than Fig 2 . please help me to find a reason for that. What are the sectional properties...

Please help me to find a SELF DRILLING screw to fix aluminium(3mm THK) to aluminium (3mm THK). The screw fixed inside a 12mm groove so we cant insert hexagonal socket .The Max Head size is 9-10mm Only and Pan head or Philips head preferred . Please suggest some world class screw manufacturers.

How to give impact load in staad. i need to check the system will pass the soft body ( 300 joule) and hard body impact test as per the EOTA and ETAG 003. Whats the general procedure to convert the energy (joule or Nm ) to load ( to model in staad ) . Please help me to find a solution .

Im designing a hanging ceiling for external use. I have to follow ASCE as per the project specification. But when i check the code (ASCE )no separate wind load calculation recommendation for Ceiling. If we consider it as components and cladding (C/C) All the hanging rods (M10) fails because of...

I am designing steel framed structures to support ceilings. All the hangers are fixed with ceiling with expansion anchors. In staad model if we consider the connection as pinned it fails in deflection but all the utilization ratios are very small. how we can conclude whether it is pinned or...

Hello All, Im doing the structural design of partition walls inside a office building. On the top of the wall a small book shelf attached to the wall . while checking the code the min load is 0.25 kN/m2 ( As per IBC 2006 - 1607.13). I think its very small load. Can you suggest any codes for...
