CTSRC structure is a new composite structural system for residential buildings and it consists of walls and floors which are made of the prefabricated steel skeleton and the infill of concrete. Four pieces of CTSRC shear wall specimens and one piece of RC shear wall specimen are tested under low cyclic lateral loads to study the final failure modes and analyze its structural seismic performance. It shows that the CTSRC shear wall structure possess adequate bearing capacity, fine seismic performance and ductility. CTSRC shear walls are better than RC shear walls in the seismic behavior, and it could replace traditional shear walls structure applying to practical engineering. Inserting ring used for connecting profile steel can transfer stress well and it is recognized as a reasonable construction measure.

As a new type of structural system, the cast-in-situ reinforced concrete grillage shear wall system has functions of formwork, strength and heat preservation at the same time. It is suitable for residential buildings in seismic and non-seismic areas. The results of quasi-static tests on 20 specimens of small and large grid size grillage shear walls with different shear span ratios show that: both of small and large grid size grillage shear walls have excellent seismic performance; shear or bending deformation of horizontal and vertical limbs dissipate seismic energy so the elastic-plastic deformability of grillage shear walls meet the requirements of shear wall structure under strong earthquakes; the bearing capacity of grillage shear wall was calculated with formulas used for solid RC shear walls. The equivalent thickness of grillage shear wall equalized as solid shear wall is determined by elastic finite element analysis.

Lateral Stiffness Ratio

There are two typical seismic damage characteristics to the masonry building with frame shear wall structure at first two stories, and the lateral stiffness ratio of the third storey to the second storey is one of the key factors mostly affecting the seismic performance of this kind of building. However, some factors are not considered sufficiently in current Chinese seismic codes. According to the theory of performance-based seismic design, the seismic performance of this kind of structure is analyzed in this paper by taking time-history analysis on models which with different storey stiffness ratios. The results show that when the lateral stiffness ratio controlled in a reasonable range, the upper masonry deformation can be ensured in a range of elastic roughly, and the bottom frame can be guaranteed to have sufficient deformation and energy dissipation capacity. Finally, according to the seismic performance characteristics of masonry building with frame shear wall structure at first two stories, especially the characteristics under strong earthquakes, a method of simplified calculation model for the upper masonry is discussed in this paper.

In the paper, the equation of stiff characteristic coefficient of shear wall structure with unidirectional wall frames was derived, the deformation characteristics of structure with different wall frames ratio and height were analyzed. Through pushover analysis, the seismic performance of structures were evaluated by interlayer displacement angle and plastic hinge development process. Under earthquake action, increase of wall frames ratio will make plastic deformation increase and maximum interlayer displacement floor move down.The bottom of structure is the weak region, the short wall limbs of wall frames are the weak structural vertical members. The research results show that the wall frames bring adverse effects on the structural seismic performance, so the different design meathods should be carried out according to the overturning moment proportion of wall frames.

The paper analyses the damages of the frame structure with bottom weak layer considering of Wenchuan earthquake. The analysis result indicates the current design method "pure frame" is imperfect. The related research shows that important reason for the bottom weak layer’s breakage is the stiffness mutation which is caused by the filler wall. If we arranged partial shear wall structure in the bottom weak layer, the adverse effects of stiffness mutation will be decreased, and improve the seismic performance of the frame structure with bottom weak layer.
