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.

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.

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.

about statistical probability method in his book.Retaining walls are important part of the highway system. After the Wenchuan earthquake, 375 damaged retaining walls in 3 provinces had been surveyed, the relationship between seismic damage extent with the intensity, the relative location with the fault line, the heights of retaining walls, construct methods, and foundation conditions were analyzed.

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.

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 seismic damage and loss of service of pipeline engineering may have great influence on the society, so the seismic research of pipeline engineering had always been highly valued. In this paper, the seismic damage characteristics of pipeline and vulnerability of water pipeline system in Wenchuan earthquake are analyzed, some revelations have been presented. The seismic capacity of pipeline engineering in some towns and cities was not adequate, the pipeline systems suffered great losses in Wenchuan Earthquake, and effective seismic countermeasures should be considered in design and construction of water pipeline system in order to improve this situation.

The curved bridges suffered severe damages or even collapsed during 2008 Wenchuan Earthquake. A field survey of seismic performance of RC curved bridges was examined. Damage patterns and the probable causes of RC curved bridges including Baihua bridge and ramp bridge of Huilan interchange are presented and analyzed in this paper. The main failure was pure shear failure or shear-flexural failure of the pier columns. Bearings and expansion joints damage were another common failure pattern. Lesson learned from the damage of RC curved bridges in this earthquake, the recommendations on the seismic design of RC curved bridges are presented involving ductility of bridge columns, design of curved bridges, design of bearings and devices preventing girders falling down. Suggestions for the future seismic design and retrofitting of RC curved bridges are also presented in moderate to severe earthquake area.

The seismic damage investigation on 488 buildings in Anchang County during Wenchuan earthquake was performed and the investigation data were analyzed, especially for the school buildings. 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 Type-A buildings are most severe, those of the Type-B buildings are second while those of the Type-C buildings are the slightest. Moreover, the damages of Type-B and Type-C school buildings are a little higher than the average level of Type-B and C buildings in Anchang County.
