ABSTRACT

An all-steel bamboo-shaped energy dissipater (SBED) composed of a bamboo-shaped core and a buckling-restrained tube was recently proposed. However, systematic parametric studies on the effect of experimental parameters of SBED have not yet formed, as well as design method. In this paper, the numerical model established for SBED was firstly calibrated based on previous test results. Then, five series of numerical cases were conducted to evaluate the effects of different geometrical parameters on the performance of SBED. Besides, a design method of SBED was further provided in terms of certain demands of bearing capacity and deformation of SBED.

新型全钢竹形消能器的参数化研究与设计方法

摘要

最近提出了一种由竹形芯和屈曲抑制管组成的全钢竹形消能器（SBED）。然而，关于SBED实验参数影响的系统参数化研究，以及设计方法尚未形成。本文首先根据以往的测试结果对建立的 SBED 数值模型进行了标定。然后，通过五个系列的数值案例来评估不同几何参数对SBED性能的影响。此外，针对SBED承载能力和变形的一定要求，进一步提出了SBED的设计方法。
