Architectural steel structures can be considered as a hierarchy, composed of the building, the system, the subsystem, the member and the material level. This paper studies LCCO_2 corresponding to each of these levels and discusses corresponding means of reducing LCCO_2 To illustrate, calculations were made with respect to an building. If the subsystem level having a building life of 1000years should be feasible, it would be possible to reduce LCCO_2 about 50%, compared to the case rebuilding every 100years. In the case of rebuilding every 100years, if reuse at the member level should be feasible, about 30% reduction of LCCO_2 would be possible. Any recycling at the material level would permit a cut of about 20% in LCCO_2 Long service life, reuse and recycling and three primary measures for reducing environmental burden in building field. A sustainable building structure enables the environmental burden to reduce. This structural system, which is a kind of damage-controlled structure, consists of semi-rigid beam-column connection with buckling restrained braces like knee brace. In this study, full-scale experiments of column-beam joining method were carried out. Based on these results, structural models, which modeled the connection, were analyzed, and the systematization of this structure verified.

建筑钢结构可以看作是一个层次结构，由建筑、体系、子系统、构件和材料层组成。本文研究了每一级对应的LCCO_2，并讨论了相应的降低LCCO_2的方法，并以一栋建筑物为例进行了计算。如果建筑寿命为1000年的子系统级是可行的，则与每100年改建一次的情况相比，LCCO_2有可能减少50%左右。在每100年重建一次的情况下，如果成员级的再利用是可行的，那么LCCO_2将有可能减少30%左右。在材料层面的任何回收都将使LCCO_2的使用寿命减少约20%，再利用和循环利用，以及减轻建筑领域环境负担的三项主要措施。可持续的建筑结构使环境负担得以减轻。该结构体系是一种损伤控制结构，由半刚性梁柱节点和屈曲约束支撑组成。本文对梁柱连接方法进行了足尺试验。在此基础上，对建立连接关系的结构模型进行了分析，验证了结构的系统性。
