Vertical combination of different seismic resisting systems, permitted in the design codes such as ASCE/SEI7-16, is an effective choice for structural mid- and high-rise buildings. In analysis structures, according to codes, estimate fundamental period vibration needed. On other hand, there no simplified equation compute mixed buildings with vertical systems. this study, by using Rayleigh’s met...

Due to the fact that the buckling-restrained brace core yields subject to both tension and compression, it can adsorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important objectives of seismic standards is safeguarding the appropriate ductility for the structures because the structures, in case of being ductile, can dissipate a considerable...

Eccentrically braced frames (EBFs) are typically employed in seismic design because they integrate the benefits of concentrically and moment-resisting frames, providing both high elastic stiffness ductility. However, effect fire on structural stability EBFs has not been well documented. Object-oriented techniques used software program development have become popular recent years, primarily thei...

In recent years, seismic design of structures has been undergoing significant changes due to increasing demand for optimization and minimizing the level of damage and reducing the cost of structural repairs. Development of analytical methods and remarkable improvements of computer performance have been among the factors which influenced the design of structures. A lot of research has been condu...

Abstract This paper investigates the effect of inherent damping modeling on computed seismic response and collapse performance selected seismically isolated buildings. The analyzed buildings were designed by procedures ASCE/SEI 7–16 standard. structure is a six‐story perimeter frame building with special moment resisting frames or concentrically braced (SCBF) for location in California. Three d...
