The code below plots 'k' along the y-axis and 'theta' along the x-axis.
I would like help on the following, for which I do not know how to write out the code in MATLAB:
1. I want to extract only those 'theta' values corresponding to integer values of 'k'
2. Then, use the above 'theta' values...
Hello,
I would like to know what definition of "strain" is used for CABLE ELEMENT by SAP. I am performing nonlinear analysis of cable-truss structures and am trying to write a Matlab code to compare with SAP results. I recognize that the source of discrepancy is probably in the definition of...
Hello,
I am performing an analysis of a prestressed cable-truss in SAP. On running the analysis, I obtain an error saying -
"NULL GLOBAL DOF UY IS COUPLED TO A NON-NULL GLOBAL DOF AT JOINT 21
COSINE BETWEEN COUPLED DOF = 0.923880"
Can someone help interpret this?
Thanks
Hello,
I am trying to analyze a 3-hinge arch to find the buckling load. I have attached the SAP file here, which has the modeling done correctly. I suspect I am not doing to P-delta analysis correctly.
My objective is to apply equal value point loads at the two knees and the top ridge...
Hello,
I would like to know how to model 3D cable-strut structures in SAP 2000. There will be no externally applied loads and self-weight will not be taken into account. Which means, on analysis, the structure should find a new equilibrium position resulting in internal forces (prestress...
