摘要

提出了一种裂纹结构的动力模拟方法，以确定裂纹结构的动力响应，评价其结构性能。该程序使三维裂纹结构的模拟成为可能。随机产生激振力来模拟阵风。假设结构保持在弹性范围内，这允许每个有助于其动态响应的模态解耦。结果表明，损伤的存在导致结构模态参数的变化，其精度与其他类似的简单结构方法相当。因此，本文提出的方法是评估三维开裂建筑结构动力性能的可靠方法。

Dynamic Simulation of Cracked Buildings for Damage Detection

A dynamic simulation method for cracked structures is implemented to determine their dynamic response with the purpose of evaluating their structural behavior. The procedure makes possible the simulation of three-dimensional cracked structures. The excitation force is randomly generated to simulate wind gusts. It is assumed the structure remains in the elastic range, which allows for each mode that contributes to its dynamic response to be decoupled. The results indicate that the presence of damage causes changes in the modals parameters of the structure as accurate as other similar methods proposed for simpler structures. Therefore, it is concluded that the proposed method is a reliable way to evaluate the dynamic behavior of three-dimensional cracked building structures.

期刊介绍： In order to maintain a reasonable cost for large scale structures such as airframes, offshore structures, nuclear plants etc., it is generally accepted that improved methods for structural integrity and durability assessment are required. Structural Health Monitoring (SHM) had emerged as an active area of research for fatigue life and damage accumulation prognostics. This is important for design and maintains of new and ageing structures.
