• Generating Seismic Loads

    Hello. Why do we have to generate seismic loads first and then the other loads after seismic loads? How can I find the seismic weight of the structure so that I can generate the seismic loads similar to floor loads instead of copying my DL and LL under…

  • RE: NO LOADING DEFINED FOR UBC LOAD. RUN TERMINATED.

    Hi, You have not defined seismic weight which is used for calculating base shear. For more information, please refer article 5.31.2.1 of Technical Reference Manual. Few more observations: 1. Selfweight is not provided for the entire model. So, you…

  • RE: seismic load analysis joint weight & member weight

    Yes you are required to define seismic weights through JOINT WEIGHT, MEMBER WEIGHT etc. when using the seismic load generation ( General > Load & Definition > Definitions > Seismic Definitions ) The following wiki has more explanation on this topic…

  • RE: How to add surface loads to seismic weight?

    You should not use surface elements for modeling slabs. Instead you should model the slabs using a mesh of plates. Surface elements should only be used for modeling shear walls. The element weight within seismic definition is applicable for plates only…
