Seismic performance of HSC dual systems irregular in elevation
This paper presents a study on the seismic nonlinear performance of 86 multistory dual systems irregular in elevation and constructed from normal strength concrete (with fc = 25 MPa) and high-strength concrete (with fc = 75 MPa). The applicability of the Static Equivalent Lateral Force (SELF) method...
