含水率对混凝土弹性简支梁受力特性影响分析
Effect of Moisture Content on Elastic Concrete Simply Supported Beam
摘要
Abstract
The mechanical properties of concrete are significantly affected by moisture content.At present,the researches on moisture content of concrete mostly focuses on physical test of concrete materials,but the theoretical analysis on concrete structures is rarely reported.After assuming the distribution law of moisture content along the height of cross section in simply supported beam,the explicit analytical expressions of stress and deflection of concrete beam subjected to uniform pressure can be obtained,and the stress and deflection of typical cross section under different moisture content distribution can be got for a case.The influences of different moisture content distribution on the mechanical properties of concrete beam are discussed,which provides a theoretical basis for the safety evaluation of concrete structures serving under water level fluctuation condition.关键词
