    bracings are taking moments even after assigning a truss specification ? what is the causes

  • Truss Zero Stiffness Warning

    Hi, I have created a model in the physical modeller (attached). I have defined all bracing members as trusses. I am getting errors in the cross-bracing when I run the analysis. It says "Zero Stiffness in Direction..." What is the best way to model…

  • Staad beam bracing

    I'm trying to understand the different scenarios in Staad for beam bracing. Non-Physical Member (not sure what to call this) I understand by default the program considers the length of member (node to node) as the unbraces length. So for a girder…

  • 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…

  • Double bay Braced Frame loads not equal

    Hello, I have several double bay braced frames in the building. The diagonals are 16-ga and 18-ga CFS straps (tension only members), while the end posts are HSS 6x6. I did not model a collector beam as I have a rigid diaphragm which will be provided…

  • Copy assignments in Ram Structural

    Hello In Ram Structural, I have the same arrangement of the vertical braces in several elevations, how can I copy in the other elevations?, also the fixity assignment in beams and columns. Thanks. Robinson

  • RAM Connection Seismic Provisions

    When checking the Seismic Provisions option in a CBB Connection the demand in the results output is 0 for all brace-gusset, gusset-beam, and gusset-column interface limit state checks. Is there a patch or expected fix for this?

  • RAM Connection Vertical Bracing

    Where is the option for "Additional Vertical Load" on the vertical brace member? This was previously an option and allowed the use of Case 2 of the Uniform Force Method to reduce shear demand on the beam connection?

  • Physical members & Brace failure NS (Norwegian) code

    Hi, In the following attached model I have applied physical members in STAAD (First time for me to use physical members in STAAD). This model has been erlier analysed using Robot, and from the analysis now in STAAD I can see dramatic failure in 2…

  • Undergraduate modeling 5 story structure in RAM Structural System

    Hello all, I'm an undergraduate modeling a 5 story building in RAM Structural System for a structure class. I have several basic issues: 1. Load inputs: Snow = 30 psf, LL = 100 psf, DL = 3000 kips QUESTION: Do I differ the loading between Floors…
