Reinforced Concrete Frame Structure

Basing on the finite element analysis software, the emergence of crack under the effect of gradual changed temperature load and the change of stress which are in the condition of super reinforced concrete frame structure are analyzed from the linear and nonlinear numeral simulation. The simulation shows that the structure component under the normal condition is cracked and turn into the nonlinear condition and the steel bars still works under the elastic stage. Meanwhile the actual stage which is reflected by the elastic-plastic analysis of the internal force and deformation is compared by the results which are obtained by the actual project observed results and the calculation of the simplified model. So the distribution of the stress which is caused by the structure temperature reduction is greatly evaluated by the usage of the cracking model which is nonlinear finite element and also plays an important role in the engineering project and practice.

This thesis studies deeply the crack development characteristics, failure pattern, hysteresis curve and the displacement ductility of unbonded precast reinforced concrete frame, by analyzing one unbonded precast reinforced concrete frame under low reversed cyclic load test. We build a model using finite element analysis software to the test piece model analysis, the analysis result agree well with the experimental results. So we build finite element analysis models with different design parameters to analysis the impaction for seismic performance. Numerical analysis results can provide a scientific reference for the unbonded precast frame structure design.

Earthquake Action

The stair is the vertical transport hinge among stories, it becomes a very important component. the stair is seriously damaged in Wenchuan earthquake, and it failed to perform the role for person escaping in case of emergency. a reinforced concrete frame structure with plate stairs as an example, the finite analysis is used. Calculation result shows that plate stairs have a great influence on earthquake resistant behavior of the structure. Designing without the plate staircase in consideration would lead to structural weakness in some columns and cause seriously damage under earthquake and affect the safety of structure.

Reinforced Concrete Frame Structure

To investigate the effect of the horizontal construction joint on seismic behavior of the exterior joint of the reinforced concrete frame structure, the numerical simulation of the exterior joint with the construction joint under the low cyclic loading was done. The experimental results and the numerical simulation values were compared. Seen from the ultimate load, the experiment value is 158.7kN, the simulation value is 170kN, the relative error is about 11%.Further analysis of the exterior joint of reinforced concrete frame skeleton properties, the feasibility of applying unit construction joints is verified.

Stress And Deformation

In this paper the theoretical model of reinforced concrete frame structure is established to numerically simulate and analyze its overall morphology with the finite element analysis method. The calculation results shows that at the bottom of the structure the stress and deformation is much larger than other parts with the action of constant load, live load and wind load. And with modal analysis and buckling analysis natural frequency and vibration mode are obtained to avoid resonance and predict the buckling load.
