【Abstract】 The problems existing in the formula of α_c the effective supporting length at the end of a beam, in current code are discussed in this paper. Based on the tests, a new formula for calculating α_c is presented, which is more conformable to the real conditions. The α_c under service load and the load from superstructure have beem studied,too.更多还原
