Abstract

Abstract During the past few years, several studies have been conducted in various fields of civil engineering in order to design structures that can withstand the forces and deformations that might occur during seismic events. However, more recently, building adjacent structures close to each other and more resistant to earthquakes, provided with coupling systems, has been an issue of major concern. The effects of some parameters, such as the characteristics of adjacent structures and those of the coupling system, on the choice of the separation distance, were investigated using a program that was developed using MATLAB. This article aims to present a study that is intended to determine the parameters characterizing the coupling system. Moreover, the influence of rigidity of the structure was also examined. For this, three examples were investigated: a flexible structure, a rigid structure, and a very rigid structure. The results obtained from the numerical study made it possible to show that knowing the characteristics, number, and arrangements of the coupling systems can be used to find the minimum separation distance between two adjacent buildings.

被动耦合对相邻结构地震相互作用优化的影响

在过去的几年中，为了设计能够承受地震事件中可能发生的力和变形的结构，在土木工程的各个领域进行了一些研究。然而，最近，建筑相邻的结构彼此靠近，更耐地震，提供耦合系统，已成为主要关注的问题。利用MATLAB编写程序，研究了相邻结构特性和耦合系统特性等参数对分离距离选择的影响。本文旨在提出一项旨在确定表征耦合系统的参数的研究。此外，还分析了结构刚度的影响。为此，研究了三个例子:柔性结构，刚性结构和非常刚性结构。数值研究结果表明，通过了解耦合系统的特性、数量和排列方式，可以求出相邻建筑物之间的最小分离距离。
