i`m trying to get the time hystory function for ETABS input. However i`m having a trouble how to get it from NGA WEST site. i just don`t understand how to get the function to etabs file. Would you guys helping me? best regards

Hello, I`ve a 10 storey building with 1 + 1/2 basement ( i called that because the top basement just half embeded). the total embeded height is about 4.5 meter. i used prestressed driven piles for tower foundation, i`m also put some bored piles in foundation slabs to restrain flood load (some...

hi guys, i`m using the boussiqnesq method for stress distribution on both case. i`m familiar with hand calculation of settlement analysis of shallow foundation, but for the deep foundation, it`s different story. thank you for all your feedbacks, i`m really appreciate it

i tried using settle 3D software. usually, the geotech engineer gives the second result (the distributed one) from previous projects. is there any suggestion how to make a proper model?

Hi there, I`m actually a structural engineering, trying to understand how to get a proper model of 10 storey building on analyzing settlement. i`m use pile caps and tie beams as the foundation, the top of pile caps is just the same as the foundation slabs. i`m getting confuse about the proper...

thanks JAE & KootK. You`ve got the point about beam hinges moment frame. I just doubt that the wall and beam combination could be considered as special moment frame instead of dual system (walls + frame). I`ve applied earthquake load in orthogonal direction + rendundancy factor (1.3) + Vertical...

According ASCE 7-10 R for dual system is 7 while special moment frame is 8. My project is reinforced concrete building.

Hello, I`ve got a project that only allow me to put some shear walls in one direction (say Y direction). My intension is to design the building as dual system in Y direction, but special moment frame in X direction, despite some girders connected to shearwall`s weak axis. Is that legit to...

i just install my etabs version 9.74 but when i open it, some text don`t fit in the message box so i cant see it clearly. so anybody know how to fix it? i can`t see the option because the text is merged by the box
