Influence Of Resisted Horizontal Vibratility And Stability Ability To The Reinforced Concerete Column By Pre-stressing Force

Resist the weaker characteristic of horizontal vibration function in accordance with the ordinary reinforced concrete column, and thinks over by way of the pre-stressing force to fix up fixed quantity muscle in the column and exerts effective pre-stressing force in order to improve this condition. This article, to the resisted horizontal vibration function of the reinforced concrete to think over pre-stressing force to influence down column, stable effect as well as and the resisted horizontal vibration function constructing the entire pre-stressing force concrete framed structure built spreads out fixed research is chiefly worked and the conclusion as follows from this(1) Base on the harmonious analysis method is met an emergency in the section, and that the derivation reaches the horizontal that the reinforced concrete column is thought over that the pre-stressing force influence down loads - formula is found the solution in the displacement, and raises the calculation efficiency by way of matlab procedure, and in order to analyze the reinforced concrete column is resisted that the horizontal vibration function provides the fixed theory basis.(2) Think over to the reinforced concrete column that the pre-stressing force influences down the resisted horizontal vibration function carrying on the full course nonlinear analysis, and reaches this kind of member and ordinary reinforced concrete to go through similar development change, elasticity stage, elastoplasticity stage as well as plasticity stage that and the horizontal to study the member from cracks and subdues to the limit state is born the weight the power and stiffness changes; The various factors that the resisted horizontal of reinforced concrete column of the at the same time to influences is vibrated the function have been carried on the analysis fairly, including pre-stressing force intensity than and joins in marriage the muscle and adds the a spool pressure when more pressure in advance to compare, and reaches the various factors to resist the influence that all has the different level of horizontal vibration function to the reinforced concrete column.(3) Base on the simulation analysis has been in progress to the resisting horizontal vibration function of the reinforced concrete to think over pre-stressing force to influence the down column and the reinforced concrete column of other factors influences respectively by limited first software Ansys,; And resist the simulation analysis that horizontal vibration function and other factors influence down the function to the reinforced concrete to think over pre-stressing force to influence the down column framed structure further.(4)The reinforced concrete column of pre-stressing force influence is gone out to think over.final this article derivation, and to lose steady (lee) critical loads the calculation formula, and reaches pre-stressing force exerting the fixed level effectively to rise to lose steady critical loads, and discusses the formula application scope.
