The influence of construction measurement and structure storey on seismic performance of masonry structure

Abstract

Abstract. The damage of masonry structures in earthquakes is generally more severe than other structures. Through the analysis of two typical earthquake damage buildings in the Wenchuan earthquake in Xuankou middle school, we found that the number of storeys and the construction measures had great influence on the seismic performance of masonry structures. This paper takes a teachers' dormitory in Xuankou middle school as an example, selected the structure arrangement and storey number as two independent variables to design working conditions. Finally we researched on the seismic performance difference of masonry structure under two variables by finite element analysis method. IntroductionEarthquake is one of the world's largest natural disasters that endangers human life and property, and China is one of the countries in the world with a frequent occurrence of earthquakes, there are more than 600 times six and above magnitude earthquake occurred in the Twentieth Century in China. The Wenchuan earthquake in May 12, 2008 was the most serious earthquake since the Tangshan earthquake in 1976, which had wide range of seismic impact and highly destructive.In this earthquake, the earthquake damage on the teachers' dormitories were different, the destruction of middle school teachers' dormitory in the northwest corner of school, students dormitories and the teaching building appeared different seismic performance. This was caused by the difference between the design and construction and the arrangement of the structural measures. In this paper, we selected the five storeys Xuankou middle school teachers' dormitory as an example to study on the influence of the arrangement of structural measures and the number of storeys on the seismic performance of masonry structures and calculated the percentage of amplitude effect.

Statistical analysis of the bonding properties of the fabric-reinforced cementitious matrix for strengthening masonry structures

“…Unreinforced masonry (URM) structures are one of the main forms of building structures found worldwide. However, due to environmental actions, changes in functionality and lack of maintenance, the existing URM structures are highly vulnerable during earthquakes, such as the 2008 Wenchuan earthquake in China; this vulnerability seriously threatens the safety of human life and property (Sun et al, 2017).…”
