Nonlinear Time History Analysis for Seismic Effects on Reinforced Concrete Building
Nigerian Journal of Technological Development, 2023 A typical Reinforced Concrete (RC) building frame comprising of RC columns and connecting beams that participates in resisting the earthquake forces. Due to earthquake, reversal tension generates at both faces of a beam and column; and hence damage occur in the frame for the disability of tension carrying capacity of concrete. Therefore, the structural

Mass proportional damping in nonlinear time-history analysis [PDF]
Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015 Rayleigh damping is the main form in direct integral method for structural nonlinear dynamic analysis under seismic wave. As stiffness proportional damping usually should be neglected for its significant influence on limit time increment, reasonable mass proportional damping becomes more important in actual engineering.

Nonlinear Time History Analysis of Anti Seismic Device on Highway Bridges
International Journal of Advances in Scientific Research and Engineering, 2020 There are many earthquake suppression technologies offered by experts, one of them is the use of Lead Rubber Bearing (LRB) in civil buildings. LRB works by reducing the dynamic load acting on a bridge caused by seismic loads. It diverts the load that works through the dynamic system by maintaining a balance between the force and displacement that ...
