项目摘要

A steel structural system which consists of wide-flange beams and columns connected by using buckling restrained knee brace dampers are proposed. The knee brace dampers are made of low yield strength steel and connected to beams and columns by high-strength bolts. These bolted dampers are intended to produce advantages on the steady quality assurance related to the construction work of the structural joints and the seismic resistance of the frames against strong earthquakes. In order to actualize this system, following investigations were conducted.1) The configuration of joint elements and the buckling restraining method for knee brace dampers are indicated. According to the proposed procedures, the full-scale experimental connections for loading tests are designed and fabricated.2) Loading tests for full-scale beam-column subassemblies of the proposed structural system are conducted. The fundamental mechanical properties, namely, the elastic stiffness of joint elements, the yield limit and the collapse limit of structures are experimentally inspected.3) The effective restraining method against the lateral buckling of a beam which is connected to the columns at the both ends by the knee brace damper system is suggested and its effectiveness are experimentally confirmed. The design procedures for the buckling restraining of the beam is indicated.4) The issues concerned with construction works for the proposed structural system are investigated, namely, the shop fabricating process, the erection at the construction site, the administration of fastening ultra high-strength bolts, the development of an efficient fastening machine.5) The calculating method of the stiffness and the strength of the knee brace damper systems are indicated. An example of a structural design for a 3 story building is shown and the structural performance and the cost for construction are compared with an ordinary moment resisting frame.

提出了一种由宽翼缘梁和柱组成的钢结构体系，通过屈曲约束膝撑阻尼器连接。膝撑阻尼器由低屈服强度钢材制成，通过高强度螺栓与梁、柱连接。这些螺栓阻尼器旨在提供与结构接头施工相关的稳定质量保证以及框架抗强震的抗震能力。为了实现该系统，进行了以下研究：1)给出了膝关节支架阻尼器的关节元件结构和屈曲抑制方法。根据所提出的程序，设计并制作了用于加载试验的足尺试验连接件。2）对所提出的结构体系的足尺梁柱组件进行了加载试验。对节点单元的弹性刚度、结构的屈服极限和倒塌极限等基本力学性能进行了实验检验。3）两端柱连接梁侧向屈曲的有效约束方法提出了护膝减震系统，并通过实验证实了其有效性。指出了梁的屈曲抑制设计程序。4）研究了拟议结构体系的施工工程问题，即车间制造过程、施工现场安装、超高扣件的管理。 5)给出了护膝阻尼系统刚度和强度的计算方法。以一栋三层建筑的结构设计为例，将其结构性能和施工成本与普通抗弯框架进行了比较。
