INFLUENCE OF SEISMIC POUNDING ON RC BUILDINGS WITH AND WITHOUT BASE ISOLATION SYSTEM SUBJECT TO NEAR-FAULT GROUND MOTIONS

Influence of Seismic Pounding on RC Buildings with and without Base Isolation System Subject to Near-Fault Ground Motions

Building pounding occurs between two adjacent buildings with small gap or without sufficient separation distance.It leads to damage buildings during earthquake due to impact.Many researchers have opi march in uniform investigated building pounding based on impact force reduction and energy dissipation increase, when two buildings collide with each

Big Bang Nucleosynthesis hunts chameleon dark matter

Abstract We study the chameleon field dark matter, dubbed scalaron, in F (R) gravity in the Big Bang Nucleosynthesis (BBN) epoch.With an R 2-correction term required to solve the singularity problem for F (R) gravity, we first find that the scalaron dynamics is governed by the R 2 term and the chameleon mechanism in the early universe, which makes
