The results of tests on fifteen four-column frame specimens subjected to progressive unidirectional ground shaking up to collapse are analyzed. Test structure performance is compared with proposed limits for minimizing P-∆ effects in highway bridge piers. The stability factor is found to have a strong relation to the relative structural performance in this regard. Specimens with θ less than 0.2...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

Abstract City centres of Europe are often composed unreinforced masonry structural aggregates, whose seismic response is challenging to predict. To advance the state art on these Adjacent Interacting Masonry Structures (AIMS) subproject from Horizon 2020 project Seismology and Earthquake Engineering Research Infrastructure Alliance for (SERA) provides shake-table test data a two-unit, double-le...

Extensive damage to buildings and infrastructure observed during past earthquakes resulting from the liquefaction of shallow saturated soil deposits underneath structures has demonstrated necessity for further research in area liquefaction-induced ground movement effects. This study explores utilizing helical piles as a countermeasure reduce foundation settlement investigates their seismic perf...
