Damage Investigation

People remained optimistic about the safety of the space grid structures, because the seismic damages of space grid structures were quite rare and rather light. However, two space grid structures got damaged in 2013 Lushan Ms 7.0 earthquake. The two structures are the double-layer reticulated shell structure and flatbed grid structure, namely Lushan Gymnasium and Lushan Middle School Gymnasium respectively. This paper briefly reviews the seismic damage phenomena of grid structures in historical earthquakes, and then focuses on the two damaged space grid structures in Lushan earthquake. The reason why the two space grid structures got damaged are derived from the force state analysis of the rods, ball joints and bearings. Finally, we come up with the effective advice for the seismic design and construction of the space grid structure.

Wenchuan Ms 8.0 Earthquake

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.

According to the investigation on historic structures in Zhaohua Ancient City, there are a total of 210 historic structures in the city, of which the historic timber structures account for 93.8%, namely 197 in total. In this paper, damage degrees of the historic timber structures have been determined, although the timber structures had not considered seismic design when they were built, nearly 60% of the historic timber structures are of relatively minor damage. Besides, based on the analysis on seismic damage of the historic timber structures, the failure modes of the timber structures have been concluded, namely the tenon pullout or tenon break-off, the pillar break-off, the pedestal slip and the retaining wall damage.

Damage Investigation

The seismic damage investigation data of 257 buildings in Qingchuan County during Wenchuan earthquake are statistically analyzed. The results indicate that the seismic damages of buildings with seismic design are obviously lower than those of buildings without seismic design, and the damages of the brick-wood structures are most severe, that of the bottom frame structures and masonry structures are second while that of the reinforced concrete frame structures are relatively slight.

The Wenchuan earthquake occurred on May 12, 2008 (Beijing Time) caused great economical loss and large amount of buildings were destroyed. Many of single-story reinforced concrete industrial buildings in Hanwang town located in the highly seismic region were damaged, and the damaging phenomenons are very typical. According to the damage survey and analysis of typical seismic damage for the single-story reinforced concrete industrial buildings located in Hanwang town, the damage distribution and failure characters of these buildings are summarized in this paper. The single-story reinforced concrete industrial buildings which were designed according to current seismic design code have better earthquake resistant behavior than those old single-story reinforced concrete industrial buildings and the damaging phenomenon show some new features. Finally, combining current seismic design code of our country and the earthquake damage lessons, some reasonable suggestions on the work of seismic strengthening and earthquake resistant design of the single-story reinforced concrete industrial buildings have been given.

Based on the damage field survey of the industrial building in Wenchuan earthquake, the typical building seismic damage characteristics of industrial structures were summarized and analyzed. According to the damage phenomenon, the following conclusions are derived: usually, the main structures of industrial buildings received serious damage, which roof system were distorted and collapse, bent-frame column were pressed and yielded, bracing system were tension broken or pressed and yielded; when the main structures of industrial building received minor damage, the non-structural member regular suffered relatively damage, include the end bays in the longitudinal direction, high gables, the cantilevered walls between two span with different height and the foundation. Then damage rules and reasons are summed up and damage characteristics and the corresponding design and retrofitting suggestion are proposed. At the end of the paper, it was indicated that seismic design of major structure and non-structural members of factory building must be fully complied with the Seismic Design Code, seismic assessment and seismic strengthening should be carried out at regular intervals for the existed industrial building, which served a long time and whose fortification level is unsatisfied with requirement.
