Abstract

A distribution beam loading system for metal truss radome test and an installation method belong to the field of building engineering, which are mainly used for solving the problem that a metal trussradome test model in the prior art is large in volume, is complex in transmission force, and is large in total load value that needs to be applied, resulting in design of a test loading system to be more difficult and specific. The system mainly includes a middle-layer distribution beam mechanism, a lower-layer distribution beam mechanism, a total force sensor, a jack, a counterforce beam, three upper-layer distribution beam mechanisms and six node devices, and high-strength bolts pass through node discs of loading nodes and are sequentially and downwardly connected with universal bearings, node force sensors, the upper-layer distribution beam mechanisms, the middle-layer distribution beam mechanism, the lower-layer distribution beam mechanism, the total force sensor, the jack, the counterforce beam and a radome. The system is mainly used for a loading system of the metal truss radome test.

Description

technical field [0001] The invention relates to a distribution beam loading system and an installation method for metal truss radome tests, and belongs to the field of construction engineering. Background technique [0002] It is necessary to carry out overall model tests on unconventional spatial structures: the correct application of various structural analysis techniques is inseparable from the correct modeling of the structure, and the modeling process of a new system, and the correct cognition of structural analysis engineers Related to the empirical basis, the overall model test can guide the structural analysis and modeling and check the calculation results, thus enlightening people to understand the engineering structure more comprehensively. The key to successful model testing is to determine the test loading system and ensure that the applied load reflects the mechanical performance of the space structure as much as possible. Due to the large volume of the metal t...
