To　find　out　the　effect　of　the　velocity　pulse　of　near-fault　ground　motions　on　the　structural　shock　resistance,　we　simulated　the　seismic　responses　using　three　dimensional　finite　element　model　for　high　temperature　gas-cooled　reactor　nuclear　power　plant,　in　which　four　strong　motion　records　with　the　velocity　pulse　and　the　corresponding　synthetic　time　histories　with　same　response　spectra　and　without　velocity　pulse　were　used　as　ground　motion　inputs.　Our　test　results　show　that　the　seismic　responses　of　the　high　temperature　gas　cooled　reactor　nuclear　power　plant　to　ground　motions　with　velocity　pulse　are　greater　than　those　without　velocity　pulse,　and　the　ground　motions　with　velocity　pulse　can　have　strong　unfavorable　effect　on　seismic　displacement　responses　of　the　high　temperature　gas-cooled　reactor　nuclear　power　plant.　If　the　installed　equipment　is　sensitive　to　the　displacement　response,　the　designers　should　focus　great　concern　on　the　effect　of　the　velocity　pulse　on　seismic　displacement　responses　of　the　high　temperature　gas　cooled　reactor　nuclear　power　plant.　©　2015,　Explosion　and　Shock　Waves.　All　right　reserved.
