The study deals with the damage control system of wooden houses using wood friction-based dampers subjected to earthquake motion. In this study, friction joints were developed introduce damping into shear walls. Shaking table tests also conducted investigate seismic performance two-story timber structures composed plywood walls, plasterboards and walls high devices. purpose is propose an estima...

Since the structure and foundation are built on soil, the soil is the major platform by which seismic vibrations are transmitted to the structure, and has noticeable effects on the response and behavior of structure during earthquakes. In this research, the recently introduced Performance-based plastic design (PBPD) and its modified Performance-based plastic design (MPBPD) method in which soil ...

The utilization of passive energy dissipation systems has been created a revolution in the structural engineering industry due to their advantages. Fluid Viscous Damper (FVD) is one of these control systems. It has been used in many different industries, such as the army, aerospace, bridge, and building structures. One of the essential questions about this system is how it can combine with the ...

The semi-active control system is widely used to reduce the seismic response of building structures. Its performance mainly depends on applied algorithms. Various algorithms have been developed date. Recently, machine learning has various engineering fields and provided successful results. Because reinforcement (RL) shown good for real-time decision-making problems, structural engineers become ...

Reinforced concrete (RC) frame structures with open first stories and masonry infill walls at the upper are very common in seismic areas. Under strong earthquakes, most of energy dissipation demand imposed by earthquake concentrates story, this eventually leads building to collapse. A efficient cost-effective solution for upgrading type structure consists installing hysteretic dampers story. Th...

The displacement fling-step pulse seldom signatures near-field earthquake in its ground motions. It is well recognized that the motion with velocity amplifies building drift larger than regular motion. Recent findings explain experiences minor damage to collapse not caused only by single earthquakes, which many cases are due repeated seismic performance of moment frames under studied, particula...

Multi-story, reinforced-concrete (RC) building structures with soft stories are highly vulnerable to damage due earthquake loads. The story causes a significant stiffness irregularity, which has led numerous buildings collapsing in previous seismic events. In addition the structural collapse, failure of non-structural components (NSCs) also been observed during past earthquakes. light this, thi...

The shaking of a new 24-story tall building in San Diego, California, was recorded by its seismic monitoring array during the M7.1 Ridgecrest, California earthquake July 5, 2019. is located ~340 km from epicenter event. special moment framed (SMF) steel structure with reduced beam sections (RBS) and viscous damper systems (DS). Peak accelerations indicate 0.007 g at basement level 0.044 roof le...

Abstract In this paper, the parameters optimization of a tuned mass damper (TMD) is presented to enhance seismic performance six-story steel structure based on ductility damage index. Herein, frame modeled nonlinearly in OpenSees software by concentrated plasticity model. Finally, most suitable algorithm selected among several algorithms convergence rate and objective function's values. process...
