Construction for a Large Concrete Reacting-force System

反力系统作为进行各种结构材料、结构构件和结构系统的拟静力或拟动力试验的重要设施,在结构实验室中有着不可替代的作用,作为结构试验中的反力支座,对其加载孔的定位及表面平整度要求很高。以北京建筑大学结构实验室反力系统为例,从加载孔的定位和模板支撑等方面进行总结,详细介绍了该反力系统的施工工艺。

Reacting-force system for all structural materials,structural components and structural systems of pseudo static or pseudo dynamic test is important facilities,which has a irreplaceable role in the structural lab. Reacting-force system as a structural test of anti bearing,the need of loading hole positioning and smooth surface degree is very high. Based on structure laboratory reacting-force system in Beijing University of Civil Engineering and Architecture,loading hole location and formwork support were summarized,meanwhile,the construction for reacting-force system was introduced in detail.
