I am trying to verify the results obtained by modal analysis and response analysis of a G+4 RC hill Building with the base paper results but unfortunately couldn`t. Although I have followed all the steps, the obtained Time periods (T1,T2, T3) are 1.88, 1.77, 1.47 sec while in the base paper its values are 0.51, 0.59, and 0.446 sec. In the case of the mass participation factors values are 0.75, 0.85, 0.78 (approx.) while in the base paper, these are 0.988, 0.548, 0.446 as compared to the base paper which I want to verify.
So, may anyone explain the possible error? I am using a cracked version of SAP2000.
Cracked version has nothing to do with results, only the liscense check is bypassed in the installation.
If you need to check the analysis results of your structural analysis program, first try to solve a complex problem like a structural dynamic problem. Consider a frame with hundreds degrees of freedom and subjected to a seismic load whose data can be obtained from seismic web sites.
Second solve the problem with your structural analysis program, some of the structural analysis programs supports more than one method of solution; like the mode superposition method, and the Newmark's average acceleration method.
Third compare the results like the displacement, velocity, and acceleration plots.
If your structural analysis program supports one method of structural dynamics solution, then you need to program your problem using another software like Matlab to build a code based on the average acceleration method for instance.
Using Matlab to build codes of solution is relatively easy.
Hope this is useful.
Hello everyone. Please Alireza Pourteymouri where could I find abaqus or etabs crack version?
Hola, lo mejor no usar la versión cracked genera error, compre el programa. Para edificios de varios niveles, el edificio tiene muros de cortante o solo son columnas. Esos valores del SAP son edificios esbeltos sin muros de cortantes, mentras que los cálculos parecen que incluyen los muros de cortante.
