摘要
混凝土梁弯剪试验是土木工程类专业试验教学的基本内容之一。混凝土梁弯剪试验的试验工况多,梁的布置和支撑方案多变,现有的常规单轴试验机无法满足混凝土梁弯剪试验的试验要求。为此,本文设计了一套适用于混凝土梁弯剪试验的加载装置,结合常规单轴试验机,实行一体化控制与操作,可大大减少混凝土梁弯剪试验中的安装工作量,提高试验效率。此外,还设计了一组可用于混凝土弯剪试验教学的试验梁,试验结果表明,试验梁均表现出理想的破坏形态,试验效果良好。
Bending and shear test of concrete beam is one of the basic teaching content of civil engineering experiment teaching.There are many bending and shear test schemes in bending and shear test of concrete beam,and the layout and support scheme of beam are changeable.The existing conventional uniaxial testing machine cannot meet the test requirement of bending and shear test of concrete beam.In this paper,a set of loading device which is suitable for bending and shear test of concrete beam is designed.Combined with the conventional uniaxial testing machine,the loading device can implement integrated control and operation,which can greatly reduce the installation workload and improve the test efficiency.A group of test beams which can be used in the teaching of bending and shear test are designed.The test results show that the test beams show ideal failure mode,and the test effect is very good.
