Drilled pile foundations that have been set in hard soil are generally used for buildings with shear walls. By nature, a drilled foundation can withstand moments because of the pile’s dimensions and amount reinforcement installed. This study presents structural analysis 10-story building supported by dual system structure to meet earthquake requirements. The results show that, using system, req...

This study presents a novel method for accurately predicting the dynamic behavior of multistory frame buildings under earthquake ground motion. The proposed allows approximately estimating inter-story drift ratio, crucial parameter strongly associated with building damage, its distribution along height, and maximum value location. An equivalent continuous beam model rotation at base, consisting...

In this paper, necessary and sufficient conditions are stated for the Craig-Sakamoto equation det(I − sA − tB) = det(I − sA)det(I − tB) to hold for all scalars s, t ∈ C. Moreover, spectral properties for matrices A and B that satisfy this equation are investigated.

The RC-framed building is one of the most common construction techniques for seismic-resistant structures due to its ductile nature. But seismic performance RC structure affected by various factors among which site soil condition vital. sub-soil affects time period eventually impacts earthquake force in structure, thus making variations loadings. Although several studies have been performed and...

This paper presents a simplified design procedure (SDP) for performance-based of low-rise new steel MRF buildings with nonlinear viscous dampers. The SDP uses an effective stiffness and equivalent damping multi degree-of-freedom (MDOF) model the building, which is established using linearized system (damping devices associated bracing). integrated process to achieve target performance objective...

In the present study, ten steel-moment resisting frames (SMRFs) having different numbers of stories ranging from 3 to 20 stories and fundamental periods of vibration ranging from 0.3 to 3.0 second were optimized subjected to a set of earthquake ground motions using the concept of uniform damage distribution along the height of the structures. Based on the step-by-step optimization algorithm dev...

Infilled walls are the major non-structural elements which have significant effects on the seismic behavior of structures. The shape and strength of the brick elements are the main parameters affect the strength of the walls. In addition existence of openings may have a reduction effect. To increase the strength of the wall and to improve its behavior, the borders of the openings may be strengt...
