摘要

本文研究了一种计算钢结构建筑最大地震层速的新方法。众所周知,层速是附加阻尼器钢结构设计的重要参数。人们已经认识到,需要非线性时程分析来实现对实际速度的准确评估,但这种方法对于实际工程师来说似乎是复杂和耗时的。为此,本文研究了非弹性速度比,它可以定义为钢结构的最大非弹性速度与最大弹性速度之比。这个比率是整个结构的一个独特因素,可以用来直接从弹性对应物中评估最大非弹性层速度。所提出的研究具有普遍性,既可用于普通钢结构,也可用于附加阻尼装置的钢结构。进行了广泛的参数研究,以获得简单而有效的非弹性速度比表达式。

A Simple and Effective Method to Evaluate Seismic Maximum Floor Velocities for Steel-Framed Structures with Supplementary Dampers
A new method to evaluate the maximum seismic story velocities for steel buildings is examined here. It is well known that story velocities are vital parameters for the design of steel structures with supplementary dampers. It has been recognized that nonlinear time history analysis is required to achieve an accurate evaluation of actual velocities, but this approach seems to be complicated and time-consuming for practical engineers. For this reason, this paper investigates the inelastic velocity ratio, which can be defined as the ratio of the maximum inelastic velocity to the maximum elastic one for steel buildings. The knowledge of this ratio, a unique factor for the whole structure, can be used to evaluate the maximum inelastic story velocities directly from the elastic counterparts. The proposed study is general and can be used in both ordinary steel structures as well as steel structures with supplemental damping devices. Widespread parametric studies are executed to achieve simple yet effective expressions for inelastic velocity ratios.

期刊介绍: Applied Mechanics Reviews (AMR) is an international review journal that serves as a premier venue for dissemination of material across all subdisciplines of applied mechanics and engineering science, including fluid and solid mechanics, heat transfer, dynamics and vibration, and applications.AMR provides an archival repository for state-of-the-art and retrospective survey articles and reviews of research areas and curricular developments. The journal invites commentary on research and education policy in different countries. The journal also invites original tutorial and educational material in applied mechanics targeting non-specialist audiences, including undergraduate and K-12 students.
