Performance analysis

[uzooo]

Hello everyone. I got the complete reports of the building I just built from scratch. When I put this structure into performance analysis, it comes out in the collapse zone. I know that the calculation methods are different, but still, it seems contradictory to encounter such things. Especially in the elevation curtains (denim curtains), the system has problems. I have no experience with... Where am I going wrong and how should I take precautions? I'm looking forward to your ideas. Thanks in advance ...

Re: PERFORMANCE ANALYSIS Also, as an example, Vr:29.26 tf is found in the calculation of the zero building in the S201 column. When we fix the reinforcements and perform a performance analysis, we get Vr:32.58 tf.

I would like to add one more question before the answer is received ... Although Vr>VE is large in denim curtains after performance analysis, it gives a brittle fracture error.

Hi everyone. I got the complete reports of the building I just built from scratch. When I put this structure into performance analysis, it is in the collapse zone. I know that the calculation methods are different, but still encountering such things seemed contradictory to me. Especially in the upgrade curtains There is a problem in the system (in denim curtains). I do not have experience in performance analysis... I am looking forward to your ideas about where I am making mistakes and how to take precautions. Thanks in advance ...

Hi, *Change/Object Edit on all floors for K24 beam In the /Beam-Foundation-Console line, check the line "not cantilever" *Uncheck the model as shell option from the panel properties.(Cracked section rigidity is not taken into account for shear walls modeled as shell) *Analyze according to the fully rigid diaphragm option. *Perform In the ans analysis options, select the building information level "comprehensive" and the targeted performance level life safety and perform a performance analysis. In this case, the building performance level is Life Safety.

Also, as an example, Vr:29.26 tf is found in the calculation of the zero building in the S201 column. When we fix the reinforcements and perform performance analysis, we get Vr:32.58 tf. Material safety coefficients are not used in the performance analysis (item 7.4.11. a.)

I would like to add one more question before I get an answer ... It gives an error.

Since the shear walls with Hw/lw<2 are evaluated as brittle element and their Impact capacity ratios are compared according to the limit value of 1, the relevant elements seem to be shear damaged. This issue will be considered in future versions. Good work
