新型码头钢-混凝土组合面板

基于特殊需要,提出了带型钢加劲肋的钢板-混凝土组合板这一新型组合码头面板。以加劲肋形式、组合板厚度和栓钉布置为参数,进行了9块组合板的力学性能试验。试验结果表明,通过适当地选择型钢加劲肋形式、合理地布置栓钉和确定混凝土厚度,可以保证组合作用的发挥。组合板的正截面承载力可按基于修正平截面假定的极限状态计算;组合板的变形,可在按现行钢结构设计规范计算的基础上,加上考虑界面滑移影响的附加变形值予以修正。计算值与试验值吻合较好。

New Type Composite Panels of Steel and Concrete for Quays

A new type composite quay-wall panels of steel and concrete with profiled steel used as the stiffeners were proposed to meet special requirements.By using the types of stiffeners,the thickness of the composite panels and the arrangement of the goggle pins as the parameters,mechanical performance tests were made on 9 composite panels.The test results indicated that the performance of the composite panels can be well displayed if the types of steel stiffeners were adequately selected,the goggle pins were rationally laid out and the thickness of concrete was apropriately determined.The bearing capacity of normal section of the composite panels may be calculated according to the assumed limit state based on the modified normal sections while the deformation of the composite panels may be corrected according to the calculations made in line with the prevailing steel structure design codes and by taking into consideration the influence of the interfacial slipping motions.The calculated results agree well with the test results.
