Computational modelling of a four storey post-tensioned concrete building subjected to shake table testing

Shake Table Tests of Reinforced Concrete Flat Plate Frames and Post-tensioned Flat Plate Frames

A research study was undertaken to assess performance of flat plate systems constructed with slab shear reinforcement under dynamic loads. The research program consisted of shake table tests and accompanying analytical studies of two, approximately one-third scale, two-story, two-bay, slab-column frames. One specimen was constructed with reinforced concrete (RC) slab, whereas the other specimen...

Computational Modelling of Concrete Structures Subjected to High Impulsive Loading

Experiments and Simulation of Reinforced Concrete Buildings Subjected to Reversed Cyclic Loading and Shake Table Excitation

An integrated experiment and analysis research program is proposed to address the complex behavior of reinforced concrete buildings subjected to multi-directional earthquake loading and the subsequent interactions resulting from the nonlinear response of individual components that compound further the multi-directional affect of the ground motion. Results will impact a broad community ranging f...

Flexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

Dynamic testing of a four-storey building with reinforced concrete and unreinforced masonry walls: prediction, test results and data set

This paper presents the results of a series of shake-table tests on a half-scale, four-storey building with reinforced concrete and unreinforced masonry walls. Due to the lack of reference tests, the seismic behaviour of such mixed structures is poorly understood. The test unit was subjected to several runs of increasing intensity yielding performance states between minor damage and near collap...
