Embodiment Construction

[0018] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0019] The invention provides a structural mechanics experiment platform, comprising a beam, a column, a short moving column, a constraint beam, a connecting beam, a base and a sliding trolley platform; wherein,

[0020] The beam includes an upper beam, a lower beam, an auxiliary upper beam, an auxiliary lower beam and a middle beam. The upper beam and the auxiliary upper beam are used as load-bearing beams. In order to improve their rigidity, the H-shaped steel beam-spherical joint steel pipe truss composite structure is adopted. At the same time, the H-shaped steel beam-spherical joint steel pipe The experimental model of the distribution of internal force and deformation. The steel tube truss with spherical joints is connected by metal circular tubes and spherical joints, including four upper chords, six lower chords, ...

Abstract

The invention provides a structural mechanics experiment platform and belongs to the field of structural mechanics experiment teaching of the major of civil engineering. An upper cross beam, a lower cross beam, upright columns and tie beams form a space reflexive force loading frame through an assembling mode; an H-shaped steel beam in the upper cross beam, the lower cross beam and the web plates of the upright columns are each provided with a linear guide rail; the linear guide rails are provided with sliding dolly platforms, the sliding dolly platforms can be fixed at any positions of the linear guide rails; and an experiment model and a loading device are installed on the sliding dolly platforms. According to the invention, auxiliary devices such as a mobile short upright column, a constraint cross beam, an intermediate cross beam providing a horizontal counterforce and the like are configured, multiple constraints and multi-point multi-directional tensile compression loading on the experiment model are realized, and the quantity, the positions and the directions of constraint points and loading points and the dimensions of the experiment model are not restricted in an effective experiment space. The platform is of a space structure, the experiment space is open, the loading means are abundant, multiple groups of contrast experiments and autonomous design comprehensive experiments are carried out at the same time, and open experiment teaching is facilitated.

Description

technical field [0001] The invention belongs to the field of structural mechanics experiment teaching for civil engineering specialty, and relates to a structure mechanics experiment platform. Background technique [0002] Structural mechanics is a compulsory subject for civil engineering majors in colleges and universities. It mainly studies the rational form of structures and the internal force, deformation, dynamic response and elastic stability of structures under stress. Specifically, the basic tasks of structural mechanics include the following two aspects: [0003] (1) According to the functional requirements of the structure, the law of internal force distribution and the law of geometric composition, the rational form of the structure is studied. [0004] (2) Study and analyze the calculation theory and method of structural internal force, deformation, dynamic response and stability. [0005] For a long time, the teaching method of structural mechanics in colleges...
