Replaceable energy consuming beam section capable of controlling energy consuming area
The invention discloses a replaceable energy consuming beam section capable of controlling an energy consuming area. The replaceable energy consuming beam section comprises an energy consuming area beam section, and the two ends of the energy consuming area beam section are connected with H-type steel beams correspondingly. The energy consuming area beam section is divided into the energy consuming area and a connecting area, and the section of the energy consuming area is smaller than that of the H-type steel beams. The connecting area is a variable-section H-type steel beam, and the wide endof the variable-section H-type steel beam is in coinciding connection with the end faces of the H-type steel beams. Under the action of a large earthquake, the energy consuming area of the replaceable energy consuming beam section capable of controlling the energy consuming area can get into plasticity firstly due to the fact that compared with a non-energy-consuming area, the section of the beamis small and the yield strength is low, plastic deformation is generated, and earthquake energy is consumed; and meanwhile by means of a section transition manner, the energy consuming area and the non-energy-consuming area of the energy-consuming beam section are effectively controlled, the section of an end beam of the energy-consuming area is enlarged gradually, the phenomenon of stress concentration is reduced, and structural plastic deformation can be controlled.
本发明公开了一种可控制耗能区域的可更换耗能梁段，包括耗能区梁段，耗能区梁段两端分别连接H型钢梁，耗能区梁段分为耗能区域和连接区域，耗能区域的截面小于H型钢梁，连接区域为变截面H型钢梁，变截面H型钢梁较宽的一端与H型钢梁端面重合连接；在大震作用下，可控制耗能区域的可更换耗能梁段的耗能区域部分由于梁的截面较非耗能区域小和屈服强度较低，会先进入塑性，产生塑性变形，消耗地震能量；同时，通过截面过渡方式，有效地控制了耗能梁段的耗能区域和非耗能区域，耗能区域的端部梁的截面逐渐变大，减小了应力集中的现象，有利于控制结构塑性形。
