Some problems on the seismic appraiser and strengthening of building structures, such as the probability level of the objective of seismic protection for appraiser, the concept design on the seismic appraiser and strengthening, the judgement on compound seismic capability of structure and the coordination for transformation and strengthening of building structures, are investigated.

Organize the plan of anti-seismic and preparedness against natural calamities,Improve the comprehensive anti-seismic ability of the city;

Moreover, the performance of synthetic anti-jamming of the fire-control radar for the air defense forces is quantitatively evaluated.

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.
