Post-design strategy for shear walls of historic brick masonry buildings

Abstract

This paper presents a strategy for estimating the reliability level of historic brick masonry buildings in the load case earthquake. The post-design strategy enables a stan-dard-compliant and uncomplicated estimation of the shear ca-pacity, the compliance factor and the personal risk of individual shear walls (partition walls) in the form of post-de-sign tables. The post-design tables are mainly derived from the relevant standards, the currently applied pushover calculation method for historic brick masonry buildings, the building characteristics of the building stock and the site conditions of the Vienna area. The methodical approach included a detailed analysis of the existing building stock with over 200 buildings, the calculation of the existing buildings under earthquake load, a sensitivity analysis of the influencing parameters on the resul-ting compliance factor and the derivation and presentation of the post-design tables. The masonry quality could be conside-red in the presented strategy based on extensive masonry investigations of 125 historic brick masonry buildings.
