钢结构全过程人因失误影响因素重要性分析

IMPORTANCE ANALYSIS OF HUMAN-ERROR FACTORS IN WHOLE PROCESS OF STEEL STRUCTURE

钢结构的设计、施工和使用管理阶段都存在人因失误操作,大多数情况下都会对建筑质量产生负面影响。引起人因失误的因素多种多样。对钢结构全过程人因失误影响因素进行整理和归类,并利用层次分析法(AHP)对各因素进行重要性分析,得到各因素对总体影响的权重排序。各因素重要性权重排序有利于工程技术人员有针对性地加强各阶段人因失误的管理,选择最优控制人因失误的方案,提高钢结构的可靠性。减小钢结构设计、施工和使用管理各阶段人因失误概率,保障钢结构工程的可靠性水平。

Human errors which have negative effect on the quality of constructions are inevitable when designing, constructing, using and managing steel structures. There are many factors likely to cause human errors. This paper concludes human-error factors in the whole process of steel structures. Then the importance of these factors was analyzed by AHP （Analytical Hierarchy Process） method. Afterwards, the importance ranking vector of factors was acquired. The ranking vector can direct engineers in work and cut down human-error. The reducing of human- error can enhance safety of steel structures.
