• Wind Load on Tapered Section -reg.

    Dear Colleagues, current version : STAAD.Pro CONNECT Edition - Version 22.12.00.142 there was a situation where we had to find out the lateral forces due to wind on a light pole (tapered profile) and provide suitable support for the same. Wind was…

  • Can a metallic sheeting replace the bracings to resist the lateral forces - seismic forces and wind forces, to add stability of the structure?

    I have a slender structure, 5 m x 2.4 m of height 18 m. I wanted to replace the lateral bracings from level 6 m and above with the metallic sheeting, 6mm or more. I have added the plates of thickness 6mm to simulate the sheeting and by adding intermediate…

  • Floor Diaphgram and Moment Release

    0245.struc.STD 1) After applying floor diaphgram i am getting following warning *WARNING- ZERO STIFFNESS IN DIRECTION 2 AT JOINT 32 EQN.NO. 188 ***WARNING - INSTABILITY AT JOINT 980 DIRECTION = MY 2) Have i applied the moment release correctly…

  • Negative Load Case vs Negative Load Combination

    Dear Colleagues, Say if I have to apply wind on all the four sides (+x / +z / -x / -z) of an irregular structure/geometry, is it okay to consider only 2 positive cases (+x / +z) as Basic Load Case and generate 4 load combinations with 2 positive and…

  • Is it possible to apply the wind load perpendicular to a wall that does not align with a global axis?

    I have a model of a portal frame that is linked a to a revit model using structural synchronizer. The structure is a substructure, this section of the building is at 10deg to the main structure. Therefore my model does not align with the global axis.…

  • How to calculating the frequencies of a structure in the analysis together with wind load and selfweight

    I need to analyze the open metal structure which is affected selfweight and wind load. How I can set in the program to take into account in the analysis of the load and the the frequencies of a structure. I tried to install it using the formula LOAD…
