点支式玻璃建筑结构地震损伤评估模型研究

A Seismic Damage Assessment Model for Point-Supported Glass Building Structures

摘要:

地震对建筑结构的损伤轻则影响建筑完整性，重则导致建筑崩塌。近几年，地震损伤评估问题得到地震工程研究领域的高度重视，但对点支式玻璃建筑结构的损伤评估研究较少。为此，构建一种点支式玻璃建筑结构地震损伤评估模型。采用基于HHT变换的结构损伤部位识别方法判断地震中点支式玻璃建筑损伤部位，建立点支式玻璃建筑结构地震损伤评估多元联系数模型，评估点支式玻璃建筑损伤部位的损伤情况。结果表明，该评估模型对某地区点支式玻璃建筑结构地震损伤评估情况与实际结果一致，且该模型可控性较强，评估范围全面，评估效率明显优于其他评估模型，应用价值较高。

Abstract:

An earthquake may affect the integrity of building structures or cause their collapse. Recently, the damage assessment of point-supported glass building structures has been rarely investigated even though seismic damage assessment is highly valued in the field of seismic engineering. Therefore, an earthquake damage assessment model with respect to point-supported glass building structures has been constructed in this study. Further, the structural damage identification method based on the HHT transform was adopted to judge the damage location with respect to the point-supported glass buildings in case of an earthquake, and a multiple connection number model was established for conducting the seismic damage assessment of point-supported glass buildings to evaluate the damage to point-supported glass buildings. The experimental results denoted that the evaluation of the seismic damage of the point-supported glass building structure in a certain area is consistent with the actual results; furthermore, the proposed model exhibits considerable controllability and a comprehensive evaluation scope, and the evaluation efficiency is obviously better than those of the remaining evaluation models.
