Hi I want to know how we can compare 2 pushover curve, for example after I analysis structure with braces and without braces, how can i conclude and construe which is better? I can find performance point and capacity graph for each, but i do not know which of them is better for seismic design...

Hi When I carried out pushover analysis, I notice V/W ration at performance point is greater that what I calculated by UBC code. what should i do, should i analysis structure by new V/W that calculated by pushover and performance point ? thank you

Hi I want to know that does in ETABS version 9.0.4, the program checks special moment frame regulation only for I section or it can check it for all section type?

Hi Dear friens, As you know spectrum demand curve is based on 10% probibality on 50 years, but i do not know how can I define 2% probability in 50 years earthquake? anybody can help me?

Hi Dear friends When I carry out push ovre analysis with SAP2000, after looking to pushover curve there is 3 response spectra with Red colours. anybody knows what are they ? Regards

I need sap2000 pushover analysis sample. please help me

so, how can I guess P (axial force) before analysis ?

as you know we should first of all estimate column size and after that we can analysis and calculate force and moment, so my question is : first of all and before analysis how we can estimate column size for modeling and analysis in ETABS- for example 30*30 or 40*40 or....?

thank you...but I want to know how can I estimate column size before input the model in ETABS?

Hi Is there any experiment for estimate initial section size of column for modeling concrete structure in ETABS?
