How to ensure this new structure to be in elastic state under frequent earthqu ake, be mendable under design earthquake and not collapse under infrequent earthquake, especially the last item, is the problem to be solved imminently in engineering field. Center around this problem, 5 aspects of investigation are carried out as following:(1) The experiment of seismic performance of ASCCs in this new frame structure has not been reported, in order to study this problem, 9 ASCC specimens with shear steel plate are tested subjected to the horizontal low cyclic loading, in which, the shear span ratio is 3 and axial compression ratio is different. The hysteretic curves of 9 specimens are obtained. The seismic performance indexes such as energy dissipation, stiffness degradation, strength degradation, skeleton curves and ductility of this kind of column are acquired, and the seismic fortification measures including ultimate values of axial compression ratio under different seismic degree are suggested.

1新型框架结构中所采用的角钢混凝土柱抗震性能的试验研究尚未见报道，针对这一问题，本文进行了9根剪跨比为3、不同轴压比、采用钢板箍的角钢混凝土柱在水平低周反复荷载作用下的试验研究，获得了9根试验柱的滞回曲线，考察了该类柱的耗能、刚度退化、抗力衰减、骨架曲线及延性等抗震性能指标，建议了角钢混凝土柱在不同抗震等级下的轴压比限值等抗震构造措施。

The square-on-square grids set diagonally of half MERO joint have been analysed and compared according to a design example and more than thirty projects already constructed. The conclusion is that the steel con- sumption for the square-on-square grid with a span of 30 metres or so is most economical; the size and height of grid are the important par- ameters which affect the steel consumption to a high degree.
