• Dynamic Analysis

    Dear sir/admin, I have few questions that I really need to know. 1. Why we dont apply uniform member load in dynamic analysis? 2. It seems we are only providing floor load, does it mean that we have to convert member load to equivalent floor load…

  • Factor in X & Z direction and Scale factor for SRSS

    Hello Bentley support, I am working on a steel structure (Portal Reclaimer) which need to be designed in accordance to BNBC (Bangladesh Code). Can you please suggest how to assign parameter for SRSS response spectrum. However it is very similar…
  • RBE3 elements in NASTRAN - is there a STAAD equivalent?

    RBE3 elements are used in NASTRAN to distribute mass and applied force from a single node to multiple points WITHOUT introducing additional stiffness. It is implemented in NASTRAN as a SINGLE DEPENDENT NODE whose displacement is an average of MULTIPLE…
