Improving seismic performance of elevated cylindrical water storage tanks using nonlinear isolators incorporating liquid–structure interaction
Pervasive construction of elevated liquid tanks as the most important sources for urban hygienic water, and their failure under earthquake, highlighs the necessity for research toward new passive control devices. Design and use of base-isolation systems for elevated liquid tanks is propounded as a novel seismic engineering technology. To date, no special examination has been discussed in relati...
متن کاملInfluential Factor in Improving the Seismic Performance of the Kaiser Bolted Bracket Moment Connection
Following the Northridge earthquake of 1994, a significant number of steel moment resisting structural systems were damaged. Several studies have been conducted to improve the seismic performance of steel structures and specially their beam-to-column connections. One of the proposed connections for special moment-resisting frames included AISC-358 is Kaiser bolted bracket moment connection, bri...
متن کاملPerformance Based Seismic Design
Performance based seismic design (PBSD) is a cogent design approach that allows engineers to design structures with a predictable seismic performance for a specified level of hazard. In contrast to the conventional limit state or strength and serviceability based design in which a structure is designed to withstand severe load combinations and be functional under normal load conditions, PBSD go...
متن کاملSeismic performance of transportation structures
Revolutionary changes which have taken place in the USA over the past 50 years in earthquake engineering as applied to transportation structures (highway bridges, and transit and high-speed rail aerial structures) are reviewed, giving emphasis to seismic design criteria, characterization of seismic ground motions, dual strategy of seismic design, modelling and dynamic analysis, assessment of se...
متن کاملFragility Surfaces as Measure of Seismic Performance
Fragility surfaces give the probability of failure for structural or non-structural systems as a function of two parameters, the earthquake magnitude and epicentral distance. These parameters provide a unique characterization of the ground motion. In contrast, the current characterization of the ground motion by a single parameter, e.g., the Peak Ground Acceleration (PGA), can be unsatisfactory...
