摘要：通过对比分析轻钢结构与传统结构的热工性能，轻钢龙骨结构围护结构存在热稳定性差和明显的热桥现象。基于蓄热和绝热理论，引入整体优化理念，提出低层轻钢龙骨结构的热工优化策略。这些措施不仅能提高轻质围护结构的热稳定性，而且有利于消除热桥的不利影响，为低层轻钢龙骨结构节能设计及施工提供理论依据。

Abstract：Through comparative analysis on thermal property in light-steel structure and traditional building，there are poor thermal stability and obvious bridge in building envelope of light-gauge steel structure. Based on thermal theory of storage and insulation and introducing overall optimization concepts，thermal optimization tactics on low-rise light gauge steel structure were put forward. These tactics can not only improve thermal stability of light-building envelope，but also will be conductive to eliminate adverse effects of thermal bridge in order to provide valuable basis for energy-saving design and construction in low-rise light-gauge steel structure.
