对新旧水工钢筋混凝土结构设计规范抗裂极限状态可靠度的验算

Reliability Checking Calculation of Hydraulic Reinforced Concrete Members in Crack Resistance limit State of the Old Code and the New Code

对原规范和新规范的水工钢筋混凝土轴心受拉、受弯、偏心受压和偏心受拉等构件抗裂极限状态可靠度进行了验算，验算结果表明两本规范４种构件的抗裂可靠度平均水平都能满足一般要求，而新规范的抗裂可靠指标较高。

It was checked that the reliability of hydraulic reinforced concrete members under axial tension,flexural loads,eccentric compression and eccentric tension in crack resistance limit state of the old code and the new code.The calculating results from both of their averaged level of reliability indexes meet the general demands of reliability of the reinforced concrete members in serviceability limit state,and the averaged level of reliability index of the new code is higher than that of the old code.
