中美英规范在港工水电构筑物结构设计的差异

水电构筑物结构设计是港口工程设计的重要组成部分。以有限单元法为基础,对比中国的GB 50010—2010、美国的ACI 318 M-2014、英国的BS 8110-1:1997这3个规范在港工常规构筑物结构设计中的计算方法,得出中美英规范在港工构筑物的抗弯、抗剪强度、偏心受压强度计算和裂缝宽度、地基承载力验算的异同,并结合典型工程实例说明按照不同规范计算的具体步骤和差异。结果表明,按照美国或英国规范计算的港工构筑物结构的体积含钢量较大。

Differences of structural design for water and power supply structure in port engineering based on Chinese,American and British specifications

The design for water and power supply structure is an important part of the design of port engineering.Based on the finite element method,we compare the calculation methods of three specifications in the structural design of conventional structures of port engineering according to Chinese GB 50010—2010,American ACI 318 M-2014 and British BS 8110-1:1997,obtain the differences and similarities of the calculation of flexural strength,shear strength,eccentric compression strength,crack width and the checking calculation for bearing capacity of foundation in the three specifications,and illustrate the specific steps and differences in the calculation according to different specifications by typical engineer examples.The results show that the volume steel content of water and power supply structure in port engineering calculated by American specification or British specification is larger than that of Chinese specification.
