摘要根据意大利规范的规定，对一座大教堂进行了地震危险性评估。报告了基于知识过程的局部方法和全局方法所获得的结果之间的比较，该知识过程旨在描述可靠的结构分析所需的几何和力学参数。为了进行整体分析，采用了有限元技术，并采用了适当的假设来考虑砌体的非线性行为。通过一个实例，对Pushover分析方法在教堂抗震评估中的适用性进行了批判性的讨论。
ABSTRACT This paper discusses the seismic risk assessment of a Basilica-type church according to the provisions of the Italian Guidelines. A comparison between the results obtained with local and global approaches is reported, based on a knowledge process aimed to characterize the geometric and mechanical parameters required for a reliable structural analysis. To perform the global analyses the finite element technique was employed, with proper assumptions to account for the nonlinear behavior of masonry. Illustrating a case study, the paper critically discusses about the employability of pushover analysis methods for the seismic assessment of basilica-type churches.
