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柱连接的钢结构体系，该体系采用屈曲约束膝支撑阻尼器。膝支撑阻尼器由低屈服强度钢制成，并通过高强度螺栓连接到梁和柱。这些螺栓阻尼器旨在产生与结构节点的施工工作相关的稳定质量保证和框架对强震的抗震性方面的优势。为实现该体系，本文进行了以下研究：1）确定了节点单元的布置形式和肘杆阻尼器的屈曲约束方法。根据本文提出的方法，设计制作了足尺试验节点，并进行了加载试验。2）对该结构体系进行了足尺梁柱节点加载试验。试验研究了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。3）提出了一种有效抑制两端与柱连接的肘形支撑梁侧向屈曲的方法，并通过试验验证了该方法的有效性。4）研究了该结构体系施工过程中的有关问题，即车间制造工艺、现场安装、超高强度螺栓的紧固管理、5）提出了膝支撑减震系统刚度和强度的计算方法。文中给出了一个三层房屋的结构设计实例，并与普通抗弯框架的结构性能和造价进行了比较。
