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.

Multi Scale Modeling

In order to study the degradation law and seismic performance of reinforced concrete frame structure with the extension of service time under normal service environment, the multi-scale modeling of corroded reinforced concrete frame is carried out by using the general finite element analysis software ABAQUS. The correctness of the multi-scale modeling method is verified by the experimental data of corroded reinforced concrete members and single frame. The pushover analysis and elastic-plastic time history analysis of a four story reinforced concrete frame structure are carried out by using a multi-scale model. Then the seismic response and damage of RC frame structures with different service time are compared. The experimental results show that the established seismic performance model of reinforced concrete frame structure is more practical in practical application and can meet the research requirements.

Composite Wall

reinforced concrete frame structure due to its economic, applicable and good seismic performance, is a structure in the form of the construction industry in the application of the more common. Due to the functional use need to layout filled wall in the main frame structure, but infilled wall only plays the role of maintaining itself and it can not participate in the earthquake. Ribbed composite wall not only plays the role of maintenance in the frame structure, but can also participate in seismic.

In this paper, the seismic performance of a prefabricated frame structure with a local outsource steel tube bolted column–column connect is evaluated from the perspective of seismic vulnerability theory. Firstly, a simplified model of the prefabricated frame structure was constructed and validated by experiments. Then, a six-story prefabricated reinforced concrete frame structure (PRCS) and a cast-in-situ reinforced concrete frame structure (CRCS) were designed as examples to get the increment dynamic analysis (IDA) of the structure under 12 ground motions, and the two-parameter damage model was used as the structural requirement index. As a traditional structural requirement index-the maximum inter-storey drift angle cannot accurately describe the mechanism of structural damage. Therefore, two types of damage models are compared and analyzed. In addition, in order to evaluate the damage of frame structure effectively, a new damage index weighted combination method is proposed, and its feasibility is verified. Finally, the IDA curve and vulnerability curve with Kunnath two-parameter damage model and the maximum inter-story displacement angle as the requirement index are drawn. The results show that the two-parameter damage model is more accurate than the maximum inter-storey drift angle model in evaluating the seismic performance of the PRCS and CRCS. It shows that the maximum inter-story displacement angle model can overestimate the collapse resistance of the PRCS by 60.7% on average, and the collapse resistance of the CRCS by 75.67% on average. The seismic performance of the CRCS is better than that of the PRCS as the seismic intensity increases. Although the seismic performance of fabricated columns is similar to that of cast-in-place columns, there is still a certain gap in the seismic performance of frame structures.
