For further study on effective seismic design requirements of masonry structure, two masonry buildings were designed and constructed according to common structure style in towns and villages. Two full-scale buidings were subjected to earthquake using pseudo-dynamic test and quasi-static test. This paper presents crack propagation of masonry structure, hysteretic behavior, deformation and stiffness degradation under horizontal seismic action. In this experiment, deformability and ultimate bearing capacity of confined masonry (CM) with tie-column and ring-beam is higher than common brick structure (BM). Confined masonry (CM) wall maintain integrity due to constraint of tie-column and ring-beam. These tests verify that tie-column and ring-beam system is an effective seismic requirement to enhance seismic performance of masonry structure.

To study the effect of damping on seismic performance of steel frame, using the pseudo dynamic test by inputting damping and no damping to analyze the seismic performance of semi-rigid steel frame. Analysis was focused on the effect of damping on the panel zone strain, story drift and interlayer force.The conclusion was that under the more severe earthquake, the structural damping had effects on the seismic performance of semi-rigid steel frame.

In this study a kind of buckling-restrained braces (BRBs) as energy dissipation dampers is attempted for seismic performance of large span double-layer reticulated shell and the effectiveness of BRBs to protect structures against strong earthquakes is numerically studied. The hysteretic curve of such members is obtained through the simulation of the cyclic-loading test, and the equations of motion of the system under earthquake excitations are established. BRBs are then placed at certain locations on the example reticulated shell to replace some normal members, and the damping effect of the two installation schemes of BRBs is investigated by non-linear time-history analyses under various ground motions representing major earthquake events. Compared with the seismic behavior of the original structure without BRBs, satisfactory seismic performance is seen in the upgraded models, which clarifies the BRBs can reduce the vibration response of spatial reticulated structure effectively and the new system has wide space to develop double layer reticulated shell.
