Experimental result of a full scale-steel frame with a smart active control system under shaking table test has been carried out in this paper. Newly, the concept of smart structure has been broached to the extent of structure control. The NEURO-FBG control system, which is composed of both neural networks and fiber Bragg grating sensors, has been theoretically analyzed and simulated to effecti...

Structural vibration control is one of the most important features in structural engineering. Real-time information about seismic resultant forces is required for deciding module of intelligent control systems. Evaluation of lateral forces during an earthquake is a complicated problem considering uncertainties of gravity loads amount and distribution and earthquake characteristics. An artificia...

This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...

Teachers and students often suffer from the same disaster. The prevalence of PTSD in students has been given great attention. However, in acting as mentors to students and their families, teachers are more likely to have vicarious and indirect exposure via hearing stories of their aftermath and witnessing the consequences of traumatic events. There are limited data pertaining to the prevalence ...

Accurate prediction of the intensity and variability of strong ground motions for future large earthquakes depends on our ability to simulate realistic earthquake source models. While there has been considerable progress in characterizing the complexity of earthquake ruptures, recent devastating earthquakes have exhibited rather unexpected behavior. Moderate-size events occurred with surprising...

1 a r t i c l e i n f o a b s t r a c t Keywords: Balochistan earthquake Chaman fault Makran megathrust earthquake source model image geodesy We analyse the Mw 7.7 Balochistan earthquake of 09/24/2013 based on ground surface deformation measured from sub-pixel correlation of Landsat-8 images, combined with back-projection and finite source modeling of teleseismic waveforms. The earthquake nucle...

BACKGROUND Earthquakes in developing countries are devastating events. Orthopaedic surgeons play a key role in treating earthquake-related injuries to the extremities. We describe orthopaedic injury epidemiology to help guide response planning for earthquake-related disasters. METHODS Several databases were searched for articles reporting primary injury after major earthquakes from 1970 to Ju...

Owners of building portfolios in earthquake country have several data-related seismic risk mitigation concerns: Before an earthquake, they need to know the locations and seismic characteristics of their buildings to know which might pose a potential seismic risk. They also need the ability to assess and prioritize riskmitigation efforts, and to develop emergency response plans. Immediately afte...

An earthquake source mechanism is described from the standpoint that the dynamic characteristics of friction play a more important role in the dislocation motion than the boundary condition does. By considering an earthquake dislocation as a slip motion in a mechanical system involving friction, which depends upon velocity during slip, a displacement time function G(t)=1-exp(-t/τ)(1+t/τ) which ...
