The invention relates to the technical field of building structure experimental equipment and discloses an adjustable height experimental connection device for column members. A column member is vertically arranged, a horizontal actuator is connected between the column member and a reaction wall, the column member acquires vertical compressive stress from its upper end, an upper positioning blockis integrally arranged at the bottom of the column member, a lower positioning block is arranged at the lower end of the upper positioning block and is fixed to a foundation beam, the upper positioning block is positioned via the lower positioning block, the lower end of the upper positioning block is provided with a first raised tooth portion, the upper end of the lower positioning block is provided with a second raised tooth portion engaged with the first raised tooth portion, and after being engaged, the upper positioning block and the lower positioning block are releasably fixedly connected via bolts. The upper positioning block is supported by the lower positioning block so that experimental positioning need is met; as the upper positioning block and the lower positioning block are releasably connected, the column member can be arranged at different vertical heights by changing with a lower positioning block of different thickness.
Description
technical field [0001] The invention relates to the technical field of building structure test devices, in particular to a height-adjustable column member test connection device. Background technique [0002] my country is one of the countries with the most earthquakes in the world. Since the founding of the People's Republic of China, the collapse of building structures caused by several earthquakes has caused a large number of economic losses and casualties. Since building structures mostly rely on their lateral force resistance to resist earthquakes, in order to study the response of building structures under earthquakes, corresponding horizontal quasi-static tests (horizontal low-cycle repeated loading) test research is essential. [0003] At present, the application of horizontal force in simulated static test in civil engineering test depends on the actuator device fixed on the reaction wall of the structure laboratory to provide. However, since the anchor hole distan...
