Using characteristic description to define High-Tech fields is mainly expressed by the summary of design thought, material application,structure treatment and construction properteis. In the 1950s, Early High-Tech school focused mostly on technology application and standardization ; in the 1970s, they emphasized industrial techinic, mainly using industrialized steal profil, glass, plastic, metal sheet and tightwire of mass production to display industry succes. In 1990s, late High-Tech school proposes durable developpement concept, to pay attention to tract, to bring importat emation factor into conception, to improve energy using rate, to protect ecological environment, and to creat comfortable environment.

借助一些特征的描述来界定高技术的范畴，主要表现为设计的思想精神、对材料的运用、结构的处理及施工特点等方面的归纳和总结。20世纪50年代早期高技派集中在高技术的采用与构件的装配化、标准化；20世纪70年代强调表现工业技术，主要使用工业化批量生产的型钢、玻璃、塑料、金属板和钢索这些材料炫耀工业成就。20世纪90年代后新高技派，倡导可持续发展理念，注重场所地域性，更发挥情感在设计中的重要因素，用高技术来提高能源使用率，有效地保护生态环境，营造舒适宜人的环境。

Considering the behaviors of unbonded prestressed concrete beams and steel reinforced concrete columns, a kind of nonconforming beam-column element was constructed and the analysis precision was improved. Loading and reloading paths were introduced into the constitutive relationship of concrete. It is helpful to the analysis program to trace the full-range mechanical behavior of structures including the descending part and the hysterisis characteristic under cyclic loading.

考虑无粘结预应力混凝土梁、型钢混凝土柱等结构构件的受力特点，构造非协调梁柱单元，提高了分析精度；混凝土的本构关系中，引入卸载路径和再加载路径，使得分析程序可以追踪包括下降段在内的结构全过程力学行为，以及反复荷载下结构的滞回特性。

Based on the test results and numerical analysis, rigidity degradation rules and hysteretic rules are analyzed. A trilinear hysteretic model considering rigidity degradation is proposed for steel reinforced high strength and high performance concrete frame joints. The proposed restoring force model tallies with the test curves, which can be a good reference for seismic design of SRC structures.

3根据试验所得的滞回曲线和骨架曲线，分析节点的滞回规律及恢复力特性，提出了适合于型钢高强高性能混凝土框架节点的恢复力模型，为节点抗震性能研究和非线性地震反应时程分析提供科学的理论基础。
