先张法张拉台传力柱的设计

Design on Transfer Column by Streching Bed of Pre-tensioned Method

本文简单地介绍了先张法张拉台的槽式台座中的砼传力柱的设计思路。同时举例说明传力柱横截面的尺寸、配筋及横向联系梁的长度、间距。对于传力柱端部受力不均匀的问题 ,用增加纵向受压钢筋面积 。

This paper introduces a design of applying pre-tensioned method to stretch the reinforced concrete transfer column in the channel base. Meanwhile it illustrates by example the cross section , size, distribution bar of the transfer column and the length, structure distance of the tie beam do not treat evenly pressure to the transfer column end. We can solve this problem by increasing longitudinal pressure-receiving area of reinforcing bars, increasing steel plates and dense hoping bars.
