BRIDGE STRUCTURE LOADED BY TERRORIST CHARGE
Abstract eng: During explosion of terrorist charge the structure is loaded by the blast wave. The charge mass of 100 kg TNT was situated firstly above the bridge floor and secondly under the bridge on the level of terrain in the vicinity of one its piers. The reinforced concrete continuous four span bridge beam of chamber sections, supported by thin square piers was used for the determination of the dynamic response of the whole structure. The dimensions and distribution of structure parts were modelled while respecting the structure geometry and its dimensions, in order to obtain the most precise model of the bridge’s mass and stiffness. The calculated bridge response in time histories of displacements and angles of rotation of bridge parts are used for structure assessment.
