Study On Wind-Resistance And Seismic-Resistance Of The Beam-suspending Water-pipeline

Beam-suspending pipeline for tansporting water is an import constituent of Lifeline engineer. And it's weak part of pipeline system, ofen breaking off water supply , evenmore bringing a lot of loss .But specification for beam-suspending pipeline for tansporting water has not promulgated in our country yet. There is also no concrete prescription for aseismatic design of beam-suspending pipeline for tansporting water Structure .And wind-resistance design according to Specifications for building structure. The study on seismic-resistant and wind-resistance doesn't get enough attendance at present. So, for the secrurity and credibility of the beam-suspending pipeline structure, it is necessary to study of seismic-resistant and wind-resistance for beam-suspending pipeline structure .In this paper ,based on the basic theory of wind engineering and the function mechanic of wind, building the formula of wind load which based on pulsatile-coefficient wind load of beam-suspending pipeline , analyze beam-suspending pipeline engineering which using this paper result would be proven it is safety through compare with another method of wind load calculation.Set up the beam-suspending pipeline horizontal earthquake effect calculation; considering the relation among the pipeline span, study the horizontal earthquake effect according to integer model. Input EI—Centro wave, beam-suspending pipeline earthquake response appearance, analysis the wreck mechanism of beam-suspending pipeline under earthquake effect.Proposes the optimal earthquake intensity based on reliability, make the design of aqueduct economic and optimal in different security levels. Popularize this thought to the aqueduet resist-wind design. Put forward some measures of the antidetonation and resist-wind, according to power characteristic from wind and earthquake.
