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.

Several earthquakes record that the residential fills always suffer severe damages. In order to know the seismic damage mechanism and evaluate the damage extent of residential fill ground, research is carried out on two fill grounds in the eastern part of Kyoto basin. The research includes field survey about terrain condition, geological condition, development history, disaster condition during 1995 Kobe earthquake and surface wave explorations. Some remarkable conclusions are summarized as follows: In Jyodo-ji area, it is a residential fill on soft alluvium ground. The geological condition is back swamp. The thickness of surface fill soil is about 1~4 meters. In Kiyomizu-dera area, it is a valley filled ground. The geological condition is hilly platform.

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 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.

The communications in the quake-hit area are always cut off from the outside after the earthquake, and the traditional seismic field investigation method calls for immense time to accomplish house-to-house investigation, which goes against timeliness of the emergency rescue. In this paper, an emergency communication and quick seismic damage investigation method based on smartphone is proposed. Towards this, an application, E-Explorer, on iOS platform is initially developed. First, in the emergency communication module, the communication is available by using the Multipeer Connectivity Framework technology even without external network. A series of validation experiments are simulated without external network, and the results prove convincing. This module enhances the possibility of communication and increases the chances for rescue. Second, in the damage investigation module, E-Explorer integrates the functions of questionnaire and picture collection for damage phenomenon recording and image acquisition, following an intensity evaluation method according to seismic index. Last, a website, which provides guidance for rescue workers and collects damage information for quick intensity evaluation, is being built.

The ability of residents and professional emergency responders to exchange information during an emergency is necessary to provide a more efficient rescue following major disasters. Simultaneously, the quick seismic damage evaluation is significant to provide guidance for emergency response and rescue after disaster. However, traditional field investigation needs immense cost in money, manpower and time to accomplish house-to-house investigation, which results in an inefficient work. Towards this, an emergency communication and quick seismic damage investigation method based on smartphone is proposed and realized with the assistant of an application E-Explorer. First, in emergency communication module, the communication is available by using the multipeer connectivity technology even without external network, which can help to deliver important information for personal survival. Second, in damage investigation module, E-Explorer integrates the functions of questionnaire and picture collection for damage phenomenon recording and image acquisition. Last, a big data sharing platform is built, to provide guidance for rescue workers, and collect damage information for quick intensity evaluation.
