Abstract

The invention relates to a space structure node fire hazard behavior experiment apparatus and a method thereof. The apparatus comprises a lifting device I, a lifting device II, a loading device, a fire source apparatus, a flue gas retaining device, a pulley and a slideway. A test piece is installed on the loading device. The loading device and the flue gas retaining device on the loading device are vertically moved in the lifting device II. The lifting device II is vertically moved in the lifting device I. The pulley and the fire source apparatus on the pulley move on the slideway. The test piece is provided with temperature and displacement gatherers in advance. An electronic platform scale and a data monitoring storage apparatus are started. A wood crib is lighted and an experiment is started. A temperature, a displacement measuring point and data changes of the electronic platform scale are observed and stored in real time. In the invention, mechanical behavior and temperature rise behavior experiment research under a fire hazard can be performed on various kinds of space structure nodes with different constrained conditions, the apparatus can be simply assembled, operation is safe and simple, abundant data is acquired so as to develop overall collapse destruction risk analysis of a space structure under different scales of latent fire hazards, and great social and economic benefits are possessed.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a space structure node fire behavior experimental device and method for performance research of space structure nodes under fire. Background technique [0002] The space structure is widely used in public buildings such as sports venues and cultural venues due to its unique modeling effect. As the carrier of modeling expression, the importance of nodes can be seen. [0003] At present, many fire-induced collapse accidents of building structures have caused huge losses to the lives and property of the people. Fire accidents are not immune to public buildings using space structures. Moreover, this type of building has the characteristics of rich functions, high internal clearance, and novel roof shape, which highlights the uncertain scale of fire loads, large height differences in spatial positions of structural components, node styles, various types of constituent materials, and...
