Non‐linear seismic analysis and vulnerability evaluation of a masonry building by means of the SAP2000 V.10 code

TLDR

The paper investigates using SAP2000 v.10 for seismic analysis of masonry buildings. The authors validated SAP2000 by performing static push‑over tests on two walls and then applied the code to a two‑storey Italian masonry building, using equivalent‑frame modelling, SPO on the main wall, and time‑history analyses to generate dynamic push‑over curves. Seismic fragility curves were derived from the analyses, treating seismic input as a random variable. © 2007 John Wiley & Sons, Ltd.

Abstract

Abstract The aim of the paper is to explore the possibilities offered by SAP2000 ® v.10, a software package with user‐friendly interface widely used by practising engineers, for seismic analyses of masonry buildings. The reliability of the code was first investigated by carrying out static push‐over (SPO) analyses of two walls, already analysed by other researchers using advanced programs. The equivalent frame modelling was employed in all analyses carried out. The code was then used to investigate the seismic performance of an existing two‐storey building typical of the north‐east of Italy, with the walls being made of roughly squared stones. An SPO analysis was performed first on the most significant wall, followed by a number of time‐history analyses aimed to evaluate the dynamic push‐over curves. Finally, the seismic fragility curves were derived, considering the seismic input as a random variable. Copyright © 2007 John Wiley & Sons, Ltd.
