| 摘 要： | The nonlinear analysis of reinforced concrete rectangular slabs undermonotonic transverse loads is performed by finite element method.The layered rectangu-lar element with 4 nodes and 20 degrees of freedom is developed,in whichbending-stretching coupling effect is taken into account.An orthotropic equivalentuniaxial stress-strain constitutive model of concrete is used.A program is worked out andused to calculate two reinforced concrete slabs.The results of calculation are in goodconformity with the corresponding test results.In addition,the influence of tension stif-fening effect of cracked concrete on the results of calculation is discussed.

| Abstract: | The nonlinear analysis of reinforced concrete rectangular slabs under monotonic transverse loads is performed by finite element method.The layered rectangu- lar element with 4 nodes and 20 degrees of freedom is developed,in which bending-stretching coupling effect is taken into account.An orthotropic equivalent uniaxial stress-strain constitutive model of concrete is used.A program is worked out and used to calculate two reinforced concrete slabs.The results of calculation are in good conformity with the corresponding test results.In addition,the influence of tension stif- fening effect of cracked concrete on the results of calculation is discussed. |
