[摘要] 承臺(tái)類似于深梁，應(yīng)按深梁設(shè)計(jì)?？箾_切是抗剪切的一個(gè)特例，兩者的計(jì)算可以統(tǒng)一。在設(shè)計(jì)承臺(tái)時(shí)，應(yīng)考慮外力在承臺(tái)內(nèi)擴(kuò)散的有利作用。提出了相應(yīng)的計(jì)算公式，公式與規(guī)范及現(xiàn)行的計(jì)算方法一致，但均較節(jié)約，特別是在跨厚比較小時(shí)更為顯著。

Abstract: The platform is similar to the deep beam, the design of which should accord with the design ofthe deep beam. The punching resistance is the special case of the shearing resistance, so the calculation of these two can be unified. The positive effect of external force diffusion on the platform should be considered when the platform is designed. The relevant formulaes which are uniform with the criterion and the current calculation method were presented, all of which are economical, and especially obvious for those with less span.
Keywords:  platform;  diffusion force;  punching resistance;  shearing resistance;  bending resistance;  deep beam;  shear span ratio
