Simulation of Temperature Effects on Concrete Residual Strength of the Slab-Column Connections

Article ID: 1551


Finite element simulations were conducted to explore the effects of high temperatures on the loading capacity of slab-column connection for the concrete flat-plate structures by the finite element analysis software ABAQUS. The structure used for the simulation is a slab which thickness is 150 mm with a 300 mm square column in the middle of slab, the column height is 450mm. The size of this slab is the same as experiments conducted by previous paper [1]. Based on the results of simulation, the punching capacity of this structure not experienced high temperature can be predicted with very good accuracy. But the result from simulations underestimated the loading capacity of the this structure after it has been cooled by around 10%. This phenomenon is a little bit conflicts with the known experimental results, however, it can be adjusted by modify the material parameters built-in the software. This article is focus on how to best simulate the concrete behavior for both linear and nonlinear part under the room temperature and cooling after experience a very high temperature.
