Optimal locations of the actuators for frame active control are investigated in this article. The aim is to minimize the structural drifts by employing several actuators. By utilizing genetic algorithm, the appropriate locations of the actuators are determined. They should be placed in locations where they can minimize the maximum structural drift. To explore the capability of the proposed tech...

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...
