If we want to draw a map of seismic observation of a network, firstly, we must acquire station ground micro tremor data and process them, then compute a calibration function of magnitude(R(△)), epicenter dis-tance(△) and observation radius of station.

Ductility and seismic capacity of reinforced-block-masonry shear walls with confined boundary member;

ANSYS/LS-DYNA explicit integration procedures simulation of the foundation gravel layer to improve the seismic capacity of buildings

And the timber column and beam-adobe composite wall reinforced item are put forward according to local economic,in order to improve the seismic capacity of abode house without increasi.

From reinforcement work,formwork,concrete construction and masonry work quality questions of constructional RC column in masonry-concrete building are analyzed,at the same time corresponding improvement measures and suggestions are proposed in order to ensure the safety and integrity of structure to increase earthquake resistance capacity of structure.

Based on it, the idea that the earthquake resistance capacity for rural buildings are improved combining with the newly built houses is put forward.

In the investigation of rural dwelling houses in Shijiazhuang, the simplified standard structural models are established, the checking computation is carried out according to the national requirements of seismic design intensity and other parameters, and the earthquake resistance capacity of the houses analyzed.
