Finite Element Analysis Of The Behavior Of Joints Between Waste Glass Concrete Beam And Column

Waste glass concrete refers to the recycling of waste glass after artificial elutriation, drying, crushing screening, according to certain the fine aggregate gradation instead of common concrete natural river sand preparation and waste glass concrete. Waste glass concrete as a means of waste recycling, has very important practical significance.As a new type of green environmental protection building materials, can not only save the natural aggregate resources, and can relieve the contradiction between supply and demand of natural resources status quo, strengthen environmental protection, reduce the waste of the city and the surrounding environment pollution.At present, the waste glass concrete application is more and more widely, but research also less waste glass reinforced concrete beam-column joints.This topic using the large general finite element software ABAQUS, waste glass concrete beams cross node model is established.And monotonic load on the beam end, under the condition of low reversed cyclic loading, the mechanical properties of nodes is analyzed.Under monotonic loading, waste glass reinforced concrete and ordinary concrete beam-column joints of stress moire figure, such as load-displacement curve, observe their mechanical characteristics, failure mode.Parameters include waste glass replacement rate, the stirrup ratio, axial compression ratio, small eccentric compression, etc., set up 18 waste glass reinforced concrete beam-column joints of component model, the nodes in the section of the longitudinal stress distribution, stress distribution, reinforced force of the observed them, the failure pattern. Single parameter is not at the same time, by comparing the node component of hysteresis curves, skeleton curves, ductility coefficient, stiffness degradation, strength degradation and so on to analyze waste glass reinforced concrete beam-column joints under low reversed cyclic load of seismic performance.
