Hi
I have a query regarding the wall design. I use SD for the wall design(not to design but just check the capacity with given reinforcement). The wall is a C- shape + one of the flanges has a return wall. I have set up spectrum cases in ETABS to design.
Now I have the axial load for EQ and M2...
Hi
I am designing a box shaped core wall surrounded by two rows of perimeter columns for a 40 storey building. The wall is predominantly taking in-plane shear/moment from the lateral force. The flexural and shear demand is not significant and easily dealt with. My question will be about the out...
I am after some info on Dynamic Ecd value to use in ETABS. I may have seen Ecd = 1.35 Ec somewhere in New Zealand concrete code, but unsure where it was from because I have not got the code in front of me now.
I have heard Ec(4700sqrt(fc') or whatever) in ACI is thought to be based on secant...
Just wondered how you guys check mass/weight in ETABS model. And more to the point, how you do define the mass sources, "specified mass + self"??. the reason i ask is that the model i am dealing with at present has area mass representing sdl+some LL assigned to the floor. I thought it would be...
I have read the old thread(802-169700)regarding the usage of "Semi Rigid Diaphragm" that became available from ver 9?(Im not sure from what version to be honest).
The thread basically states that the only usage of semi rigid diaphragms is to define the extent of the diaphragm(building width etc...
HI there
I am currentlly using version 8.3.5 and wanted to achieve the accidental eccentricity (10% of the building width perpendicular to the eq direction) that NZS4203 requires.
I made some loadcase ecc+ and ecc- for x and y direction trying to get that, but it seemed that ETABS is not putting...
