The impact of modelling uncertainties on the seismic performance assessment of reinforced concrete frame buildings

In this study, effects of reinforcement corrosion such as reinforcement cross section reduction, steel yield strength and concrete compressive strength reduction on RC member capacity decrease are studied. Next, a two-dimensional reinforced concrete moment resistant frame is modeled to evaluate the effects of moderate and severe intensity corrosion on moment-curvature behavior of elements and structure seismic response under nonlinear analysis. Structure capacity curves in push-over analysis and failure curves resulted from IDA for both the structure without and with corrosion are obtained and the effects of reinforcement’s corrosion on the reinforced concrete frame seismic performance are determined through comparing the results. The results revealed that in terms of amount, place and type of corrosion in the reinforced concrete frame, value of the reduction resisting moment of elements is different. Furthermore, the outcomes of nonlinear analyses showed that the capacity of structure is reduced and its seismic performance level is changed as a result of corrosion.

Adverse Influence

This paper describes the results of an investigation into the expected seismic performance of reinforced concrete buildings constructed between 1936 and 1975. Typical design and construction features of these buildings are reviewed, including a chronological comparison of post-1935 seismic design levels. Two reinforced concrete frame buildings constructed in the 1950s were the subject of inelastic analysis, and it is found that member shear and poor joint performance tended to govern the ultimate response. An analysis procedure for evaluating the seismic performance characteristics of reinforced concrete frame elements is proposed. Case studies illustrate this method, one of which highlights the adverse influence of highly eccentric building layout.

External Loads

In this paper authors discuss the impact of genetically nonlinear application of external loads on the stress-stain state and on principal vibration modes of reinforced concrete frame structures on elastic foundation. The reader will find a methodology for integrated numerical and instrumental analysis. Six examples of linear and nonlinear FEA-models calculated in SCAD Office are given in comparison.
