Nonlinear Finite Element Modelling of Reinforced Concrete Frames Retrofitted with Shape Memory Alloy Buckling Restrained Braces
… Improvements in lateral strength capacity and residual displacements of the SMA-BRB retrofitted frames are assessed against a previously tested bare concrete frame and frames retrofitted with BRBs incorporating stainless steel and chrome-molybdenum steel core bars. Reverse cyclic finite-element …

A monitoring method for after-earthquake damage evaluation of buildings
… of the model, in particular in presence of residual displacements at the end of the seismic motion. Aiming to reduce uncertainties in the presence of residual displacements and to cancel the need of high-pass filtering acceleration signals, I proposed a sensing bar prototype instrumented …

Use of Incremental Dynamic Analysis to Assess the Performance of Steel Moment-Resisting Frames with Fluid Viscous Dampers
… as peak base shear, peak interstory drift, or residual displacement index, which were plotted versus earthquake intensity to create individual IDA curves. Sets of related IDA curves provide a useful summary of the structural behavior for a wide range of variables. IDA curves for the tests with …

Experimental Investigation into the Long-Term Seismic Performance of Dry Storage Casks
… events as demonstrated by their generally small residual displacements after ground motions and their ability to resist tip-over during the experimental testing.

Hybrid Steel Frames
… as story accelerations, interstory drifts, and residual displacements. Collapse performance evaluation was also provided. The performance of hybrid moment frames was investigated on a design space including forty-two moment frame archetypes. Two different hybrid combinations were implemented in …

Blast Performance of Hybrid GFRP and Steel Reinforced Concrete Beams
… behavior that provides reductions in residual damage and enhancements in flexural performance. This thesis presents the results of an experimental and analytical investigation on the effect of hybrid arrangements of glass fiber reinforced polymer (GFRP) and conventional mild steel …

Dynamic identification of the Augusta hybrid base isolated building using data from full scale push and sudden release tests
… of the static phase. The recordings included the displacements at the isolation level and the floor accelerations. A baseline fitting scheme was developed for the removal of the low frequency noise in the records. Application of the adjustment scheme provided reliable estimates of the floor …

Effect of Corrosion on the Behavior of Reinforced Concrete Beams Subject to Blast Loading
… the load to cause yielding decreased, the yield displacements decreased, and failure occurred earlier for all specimens. This was accompanied by increased damage to the concrete cover and the addition of longitudinal corrosion induced cracking. For the blast loaded specimens, the results …

Effect of Viscous Fluid Dampers on Steel Moment Frame Designed for Strength and Hybrid Steel Moment Frame Design
… damage measures such as interstory drift, residual displacement, IDA dispersion, base shear, and roof displacement were studied. Using IDA dispersion, the effect of dampers on dynamic instability was also investigated in this study. As a result, it was found that as the damping of the …

A Variable Stiffness Energy Dissipation Device for Vibration Control of Steel Frames
… device is very effective in reducing peak and residual displacements of these frames. A parametric study is then conducted to investigate how varying the snap-through force and snap-to distance can influence the performance of moment resisting frames when they are subjected to three levels of …
