In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...

William MoGowan, region president, made the plea for communications, urging member chapters to build a "twoway street" with region officers in handling CSBA problems. I t was Mr. McGowan's first full conference as region president and he appealed to the members to "let me know your problems . . . or I'll be yelling at you." A plea for positive thinking was sounded by Theodore C. Wenzl, CSEA sta...

In this paper, Endurance Time Analysis (ETA) method which is a new time-history based dynamic pushover procedure is introduced and its application in linear analysis of concrete arch dams is investigated. In this method the structure is subjected to gradually intensifying acceleration functions and its performance is evaluated based on the length of the time duration that can satisfy required p...

Unanchored steel storage tanks are used in industrial plants to store oil and other petrochemical liquids. In a major earthquake, such may sustain different types of damage, including elasto-plastic buckling the shape an elephant's foot, which is object research. The methodology introduced this paper consists cloud-based 1D site response analysis (SRA) pushover-based seismic performance assessm...

A multi-objective heuristic particle swarm optimiser (MOHPSO) based on Pareto multi-objective theory is proposed to solve multi-objective optimality problems. The optimality objectives are the roof displacement and structure weight. Two types of structure are analysed in this paper, a truss structure and a framework structure. Performance-based seismic analysis, such as classical and modal push...
