双面叠合装配式管廊侧墙面外抗震性能试验
Out-of-Plane Pseudo-Static Test on Double-Sided Laminated Side Wall of Utility Tunnel
摘要
Abstract
In order to study the mechanical deformation performance of prefabricated double-sided superimposed utility tunnel side wall connected by spiral stirrup sleeve bottom joint under out of plane load,two full-scale side wall specimens connected by this joint were tested under low cyclic reciprocating loading at different axial compression ratios,and compared with two cast-in-situ specimens,The effects of the bottom joint of the spiral stirrup sleeve and the vertical axial compression ratio on the seismic deformation performance of the side wall of the utility tunnel were preliminarily revealed.The test results show that the hysteretic curves of composite precast specimens and cast-in-situ specimens are relatively full,and have a good seismic energy dissipation capacity;which meet the seismic deformation design requirements of the fabricated structure;The shear deformation of the upper area of the composite assembly specimens are higher than that of the cast-in-situ specimens,and the cracks are all over the whole height range of the wall,which has good out of plane deformation ability关键词
