In recent years, Great development have been happened in the damping technique for high-rise building structure, how to build a structure which can ensure the safety of buildings in the sudden earthquake and how to adopt a new system structure which is more safe, more reasonable and more effective plays a decisive role in reducing earthquake disaster.This paper introduces the architectural stru...

In the fall of 1998, the Federal Highway Administration of the U.S. Department of Transportation initiated a series of studies related to the seismic performance of the U.S. national highway system. The research conducted under this study is intended to provide improved tools for evaluating and assessing the social costs and impacts of earthquakes on highway systems and bridges, and to reduce t...

This paper uses SAP2000 finite element software to perform nonlinear time history analysis of nine structural systems, and compares the period, total floor displacement, base shear force, vertex top acceleration structure under action an 8-degree rare earthquake. The research results show that seismic isolation damping technology can effectively reduce impact earthquakes on structures.

Process and power plant control, along with fault detection/isolation are being addressed by significant on-going research with many theoretical developments focused on improvements for all of these major industrial applications. This report provides an overview of the current key problems, recent accomplishments and trends, as well as a forecast of anticipated developments within this very imp...

This study proposes two fuzzy logic controllers (FLCs) for operating control force of piezoelectric friction dampers used for seismic protection of base-isolated buildings against various types of earthquake excitations. The first controller employs a hierarchic control strategy in which a higher-level supervisory controller operates a single sub-level FLC by modifying its input normalization f...

A small base isolation system using a new device that used friction force was developed. In this paper, dynamic characteristics of the system were investigated by an experiment using artificial seismic wave. The bearing combination of three cases, four spherical metal bearings, two spherical metal and two marble plate bearings, four marble plate bearings, was done in the experiment. The peak ac...

it has been pointed out the static lateral response procedure for a base-isolated structure proposed in international building code (ibc) somewhat overestimates the seismic story force. that is why in the current paper, vertical distribution of base shear over the height of isolated structures considering higher mode effects under near field earthquakes is investigated. nonlinear behavior of is...

Earthquakes are one of the natural hazards that occur due to sudden violent movement of earth’s surface which releases energy and has destructive power in many parts of the world. The development of recent technologies for the control of seismic hazards catches the attention of structural engineers to make the structures seismically resistant. The seismic base isolation technique is a passive p...
