Calculation Formula and Its Reliability Analysis of Shear Capacity of Lightweight Aggregate Concrete Beams/Shao Yongjian (Suzhou Institute of Science and Technology，Suzhou 215011，China)
Abstract:Based on the experimental results,the calculation formula model of shear capacity of lightweight aggregate concrete beams is put forward.The second moment of first order method recommended in the National Design Standard of Building Structures(GBJ68—84) is applied to analyze the reliability of the formula model.According to the demand of Unified Standard for Reliability Design of Building Structures(GB50068—2001),the value of parameter ω is fixed.The suggested formula and reliability can be used to design and calculate the shear capacity of lightweight aggregate concrete beams.
Keywords:lightweight aggregate concrete beams; shear capacity; calculation formula; reliability
