摘　　要：钢筋混凝土板是实际工程中应用最为广泛的结构构件之一,其设计是土木工程结构设计的基础,但目前板的挠度计算是借用由梁推导出的挠度计算公式。对我国《混凝土结构设计规范》(GB50010—2010)和美国ACI318M—08规范在挠度计算方面进行了对比分析,并设置了一组试验。研究表明:两国规范都没有很准确地反映板的挠度值,计算结果可能会影响结构的适用性和可靠度;两国规范也没有深入考虑板弯曲的双向性;混凝土板与梁相比,受力更复杂,套用梁的计算公式会产生较大误差。As ,.he most widely used structural member in the civil engineering,reinforced concrete slab,whose design is the basis of structural design, has no its own formula for deflection. At present, the formula of beam is used to cal- culate the deflection of slabs. In this paper, the accuracy of deflection calculation between Chinese and american codes for the design of concrete structure was compared and studied. Moreover,a group of experiment and four concrete slabs were designed and constructed. The results show that there are some differences between Chinese and American codes, by which the actual deflection is not well deflected and the two-way bending characters are not con- sidered. Compared with the beam, the mechanical behavior of the slab is complicated.
