In higher Seismic Design Categories, when using the equivalent lateral force (ELF) method, earthquake loads are applied as 100% of the seismic force in one direction (X or Y) and 30% in the orthogonal direction (ASCE 7 provisions).
However, when using dynamic analysis (modal response spectrum...
Hello everyone,
I am new to structural engineering, and I love to pay attention to details. I have two parts to clarify.
I need advice on the best way to design and model a dual system (special moment-resisting frame + shear walls) for seismic performance. My goal is to ensure proper...
