Problems solved by technology

[0002] In recent years, foreign scholars have carried out more relevant experimental research and theoretical analysis on the application of CFRP-PCPs composite bars in concrete structures, mainly using simply supported beams as the starting point. relatively little research
In addition, there are fewer experimental data on the plastic internal force redistribution law of CFRP-PCPs composite reinforced concrete continuous beams, and the determination of the amplitude modulation value of the bending moment is still to be studied.

Embodiment Construction

[0014] Such as figure 1 As shown, first, the test device is assembled according to the test device, which includes load sensor I1, load sensor II2, load sensor III5, screw jack 3, electronic displacement meter 4, reaction force frame 6, hydraulic jack 7; after the test device is connected , a 70T hydraulic jack 7 is used at the middle of the two spans of the continuous beam for vertical symmetrical loading. The sensor is used to measure the magnitude of the applied load; the reaction force value of each support during the test process is measured through the load sensor installed under each support, and the strain readings of the above load sensors are collected throughout the process, and the test data is recorded. On the external computer; the electronic displacement gauges arranged under the control section of the two-span mid-span of the continuous beam and above the cross-section of the two-end side supports respectively measure the deflection value of the two-span mid-sp...

Abstract

The invention provides a static loading testing method of a continuous beam. The static loading testing method comprises the steps of assembling a testing device firstly, wherein the testing device comprises a load sensor, a screw jack, an electronic displacement meter, a reaction frame and a hydraulic jack; after connecting the testing device, arranging 70T hydraulic jacks at the midspan position of two spans of the continuous beam respectively for realizing symmetrically vertical loading, wherein the two hydraulic jacks are the same in model, arranging two 30T load sensors at the contact positions of the end parts of the jacks and the reaction frame for measuring the loading magnitudes, and arranging the load sensor under each support for measuring the reaction force value of the support during testing. The static loading testing method of the continuous beam can be used for effectively testing the continuous beam, and the testing result is accurate.

Description

technical field [0001] The invention relates to a static loading test method of a continuous beam, which belongs to the technical field of machinery. Background technique [0002] In recent years, foreign scholars have carried out more relevant experimental research and theoretical analysis on the application of CFRP-PCPs composite bars in concrete structures, mainly using simply supported beams as the starting point. There are relatively few studies. In addition, there are fewer experimental data on the plastic internal force redistribution law of CFRP-PCPs composite reinforced concrete continuous beams, and the determination of its bending moment amplitude modulation value is still to be studied. Contents of the invention [0003] The invention provides a static loading test method for continuous beams, which can overcome the above-mentioned defects. [0004] In order to solve the above technical problems, the present invention provides the following technical solution...
