Steel offshore platforms are some of those structures which are built to withstand environmental and accidental loads during oil exploitation operation. Particular attention is being paid to earthquake loads in seismic active areas because it directly influences the capacity of the offshore structure installations. The uncertainties available in earthquake loads as well as in strength of struct...

A vector-valued intensity measure (IM) is shown to account for the effects of pulse-like near-fault ground motions. This class of ground motions, which are indicated by the presence of a velocity pulse, can cause large responses in structures and their effects are not well described by traditional intensity measures such as spectral acceleration at the structure’s first-mode period, Sa(T1). It ...

The relationship between the ground motion intensity measure (IM) and the engineering demand parameter (EDP) is analysed in the paper so as to identify and define the most efficient EDP-IM relationships for RC high-rise buildings. A 30-story RC high-rise building with the core wall structural system was selected as the reference building. 240 nonlinear time-history analyses were conducted for 6...

Buckling restrained braces (BRBs) have a similar behavior under compression and tension loadings. Therefore, they can be applied as a favorable lateral load resisting system for structures. In the performance-based earthquake engineering (PBEE) framework, an intermediate variable called intensity measure (IM) links the seismic hazard analysis with the structural response analyses. An optimal IM...

OBJECTIVES To determine whether any difference exists in responses to indirect moxibustion (IM) relative to thermal stimulation duration. METHODS In experiment 1, 9 subjects attended two experimental sessions consisting of single stimulation with IM or triple stimulation with IM, using a crossover design. A K-type thermocouple temperature probe was fixed on the skin surface at the GV14 acupun...

A novel intensity measure (IM), dimensionless floor displacement, is presented for evaluating the seismic fragility of freestanding rigid blocks subjected to one-sine acceleration pulses in this paper. The rocking responses are simulated using an equivalent single-degree-of-freedom (SDOF) model with a bespoke discrete damper account energy dissipation. performance various IMs compared simulatio...

Adaptive Incremental Dynamic Analysis (AIDA) is a novel ground motion selection scheme that adaptively changes the ground motion suites at different ground motion intensity levels to match hazardconsistent properties for structural response assessment. Incremental Dynamic Analysis (IDA), a current dynamic response history analysis practice in Performance-Based Earthquake Engineering (PBEE), use...

Abstract With the rapid development of high-speed railways around globe, safety vehicles running on bridges during earthquakes has been paid more attention to. In design railway bridges, in addition to ensuring bridge structure earthquake, vehicle should also be ensured. Previous studies have focused detailed analysis derailment proposing complex numerical algorithms for wheel–rail contact as w...
