金属屋面板系统承载力的实验检测方法

摘要

金属屋面板广泛应用于大型公共建筑以及工业建筑中，国内现行规范、规程针对金属屋面板系统的承载力未做详细规定，研究金属屋面板系统在各种工况下的承载力具有重要意义。提出金属屋面板系统承载力的实验检测方法，包括试件制作、加载制度、测点布置、试验现象描述以及数据分析等。通过足尺实验实例介绍实验研究的实施步骤，实验方法可供各类建筑金属屋面板承载力的检测参考。%Metal roof panels are widely used in large-scale public and industrial buildings. Because of no detailed pro- visions of the bearing capacity of metal roof panel system in our country, it is important to research the hearing capacity of metal roof panel system at various working conditions. In this paper the experiment method is proposed for inspecting the bearing capacity of metal roof panel system, including the specimen fabrication, loading grade, layout of measuring points, experimental description and data analysis. Some full-scaled experiment examples are presented to explain the implementation programs. The method of this paper can be referred in the inspection of the bearing capacity of various metal roof panel systems.
