The semi rigid diaphragms have a low flexural stiffness due to a small effective thickness and a relatively low Elastic Modulus. The effect of including the out-of-plane stiffness should be small.

Sloped Diaphragm Modeling

WebbThe code requirements for evaluating accidental torsion for dynamic load cases are implemented in RAM Frame when rigid diaphragms are used. To include eccentricity, set the eccentricity to “+ and –" for the x and y directions in the Response Spectra dialog when the dynamic load case is created. Webb1. Can you open the model in Ram Frame and initialize the lateral model? Yes – Go to step 2. No – The initialization halts at 20% or a polygon error is thrown while building the framing tables. RAMSS Polygon Intersection Error No – An error is encountered while meshing semirigid diaphragms or walls. RAM Frame Meshing and Segmentation 2. the dark tower ending
