Seismic Performance of RC Building Using SMA Device
Abstract: In the present study, the seismic performance of RC frames with superelastic shape memory alloy damper (SMAD) is investigated. Shape memory alloys (SMA) belong to a class of smart materials capable of regaining its original shape when subjected to heat at a certain temperature. Hence, SMA is used as energy dissipater and re-centering components. A numerical investigation is carried out with nonlinear time history analysis of a five-storey RC frame …

Dynamic Analysis of Simply Supported Bridge under Vehicle Loads
Abstract: The analysis of dynamic behavior of bridge structures that are subjected to moving loads has been one of the enquiry interests in recent years. Specifically in railway bridges, reverberation ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …

STRUCTURE HEALTH MONITORING AND ENERGY HARVESTING IN BRIDGE, VUPs BY SMART MATERIALS
Abstract: This artical examine the energy harvesting by the use of Smart material in the bridges or VUPs( vehicle underpass ) . For harvesting energy from bridges vibrations , there are mainly three different kinds of mechanism: electromagnetic , piezoelectric, electrostatic. among the three , the piezoelectric-based energy harvesting is a very mature one , which has been widely used . At the same time structure health monitoring can be done …

Dynamic Response of Bridges and its Effect on Soil Medium
Abstract: The analysis of dynamic behaviour of bridge structures that are subjected to moving loads has been one of the research benefits in recent years. Specifically in railway bridges, resonance ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges, especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …

Strain Life Approach for the Fatigue Evolution Model of Concrete under Constant Amplitude Bending Fatigue Loading
Abstract: Strain life approach for the fatigue evolution model of concrete under constant amplitude bending fatigue loading plays a very important role in the material properties such as the fatigue strain, fatigue modulus and fatigue damage, presented in this paper by the nonlinear fatigue evolution model, and the hypothesis of recycle-ratio-related fatigue strain amplitude that causes stiffness degradation and inelastic deformation. The fatigue evolution model of concrete under constant amplitude bending …

Experimental Investigation on Axially Loaded AASC and TVC Square Columns
Abstract: In this present project, an experimental investigation was carried out to study the behaviour of alkali-activated slag concrete (AASC) and traditionally vibrated concrete (TVC) columns under axial loading. The dimensions of the columns were 150 mm × 150 mm × 1219 mm to mimic the short column behaviour. The longitudinal steel ratio was varied for the specimens. Different criteria such as load deformation behaviour, compression stiffness and surface strain were …
