This paper examines the damage of buildings with different structures in 5.12 Wenchuan Earthquake to summarize the features of stress distribution and aseismatic performance and then presents the problems of the masonry building, frame and part of the frame structural buildings in the earthquake. The purpose is to put forward the series of technical strategies of anti-seismic design, which include the overall optimization, stiffness deployment and node strengthening economically and scientifically.

Based on the analysis for damages of masonry structure from Wenchuan earthquake, the seismic behavior of multi-story masonry school building is analyzed, and the seismic behavior with load-bearing structural system of longitudinal wall is mainly discussed. Based on the analysis and study, several problems which need more attention to the seismic appraisal and reinforcing design are pointed out, and finally the differences and correlation of seismic appraisal, as well as seismic design are discussed.

The 5•12 Wenchuan earthquake was in M8.0, Mianyang felt strongly. Majority of the buildings have varied at different degrees of damage, especially in masonry-frame structures, Which reinforcement cost much higher for repairing; The 1200 buildings in Mianyang city or it’s Suburbs were surveyed. The results showed: masonry suffered much heavier damage and masonry-frame of the mixed structure by designing, which damage were significantly lower than without seismic design. Realization of the earthquake will not be collapsed, and after a simple repair it can be used. Buildings that suffered heavy damage which combined with the relevant code requirements and research in the past, adopt specific measures for strengthening the houses.

During Wenchuan Ms 8.0 earthquake, masonry buildings have suffered severely damaged and collapsed, causing heavy casualties and huge economic losses. In this paper, based on seismic site survey data, some new phenomena and characteristics of earthquake damage in comparison with the 1976 Tangshan earthquake, such as seismic damage of large space buildings, inclined or “X” shaped crack in wall between windows or spandrel wall, stair damage, falling of precast reinforced concrete slab and horizontal crack at the bottom of structure, are discussed in detail. Then, the impact factors of seismic capacity of masonry building in Wenchuan earthquake, including construction age, seismic fortification, bay size, floor (roof) form, layer number, thickness of bearing wall are analyzed, respectively; Finally, some recommendations on seismic design and reconstruction of masonry structure by the seismic design code are proposed.

We take “5.12 Wenchuan earthquake” influence and one of the university in Mianyang urban area as the typical examples of the disaster preparedness community. We discuss how to plan the multiply disaster preparedness which in accordance to the geographical feature of hilly cities through the material properties of engineering materials research and study of the four-dimensional space disaster preparedness model.

In seismic areas, masonry construction is prone to brittle failures due to the mechanical behavior of the constituent materials and to the low capacity of force redistributions. The redistribution capacity is mainly due to the presence of horizontal connections upon the walls and to the stiffness of the roof, which is typically a vaulted structure. The modeling of the global behavior of a masonry building, taking into account the accurate stiffness of the vaults, is a major issue in seismic design and assessment. The complex geometry of the vaults can be considered as an equivalent plate, able to replicate the stiffness behavior and the force redistribution capacity of the real vault. In this study, the efforts of the authors are addressed to the definition of a plate, able to replace the vaulted surfaces in a global numerical model. The ideal diaphragm is considered as a generally orthotropic plate with the same footprint and the same thickness of the original vault. An extended parametric study was conducted in which the mechanical and geometrical parameters were varied, such as the vault thickness, its dimensions, the constraint conditions, and the possible presence of side walls. The results are presented and discussed herein, with the aim of providing useful information to the researchers and practitioners involved in seismic analyses of historical masonry construction.
