The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements measured up to 10 m and strong ground motion velocity pulses exceed 100 cm/s. As there is no concrete method for the seismic design of near-fa...

the nw-se trending tus fault is one of the active faults in the north-east of iran . geomorphologic evidences indicate that this fault is active and goes through mashhad city from near tus town. since the population and number of pilgrims in this city are high, the study of the tus fault is of great importance. hence, we have carried out a new investigation to evaluate the hazardous potential o...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...

In this paper, a simulation-based method is proposed for optimal placement of vibration sensors for the purpose of fault detection in a centrifugal pump. The centrifugal pump is modeled to investigate the effect of vane tip fault on fluid flow patterns numerically. Pressure pulsations are investigated at different locations at the inner surface of the pump before and after the presence of the f...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...

Earthquake-related fault slip in the upper hundreds of meters of Earth's surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture. We analyze centimeter-scale accuracy mobile laser scanning (MLS) data of deformed vine rows within ±300 m of the principal surface expression of the M (magnitude) 6.0 2014 South Napa earthquake. Rather t...

In this study, reservoir water level effects on nonlinear dynamic response of concrete gravity dams are investigated. For this purpose, the nonlinear behavior of the dam concrete is captured using the concrete damage plasticity (CDP) on the non associated flow rule assumption. Water in the reservoir is represented by the Lagrangian (displacement-based) fluid finite elements. The program ABAQUS ...

با توجه به این که در سیستم های صنعتی وقوع fault ممکن است منجر به خرابی کالا، خرابی دستگاه، افت عملکرد و یا تلفات جانی شود، شناسایی و تشخیص به موقع fault و همچنین جبران سازی آن از اهمیت کاربردی بسیار بالایی برخوردار می باشد. عمده ی سیستم های صنعتی را سیستم های غیر خطی و هایبرید با ورودی ها یا حالت های ناهمگون تشکیل می دهند. بنابراین شناسایی fault در این سیستم ها و تلاش برای جبران اثرات آن به کمک...

This study focuses on developing fragility-based seismic vulnerability assessment techniques for seismically retrofitted multi-column bridge bent. Fragility curves are developed using Probabilistic Seismic Demand Model (PSDM) to assess the relative performance of different retrofit methods under near fault ground motions. Two different retrofit techniques namely CFRP jacketing and ECC jacketing...
