Impact of falling debris on reinforced concrete slab

The work is devoted to the analysis of one possible limit states, for which scenario collapse floor over a remote column, as result general rancake-type occurs. An approximate method assessing progressive reinforced concrete slab multi-story building, will receive an impact from falling fragments failed structures, proposed. technique's underpinning dynamic simplified module motion, form assumed be similar that used in theory equilibrium. It elastic plate has little effect on final value deformation occurs casting linear plastic hinges. Part kinetic energy debris transferred receives impact, it theoretically classical case completeness impact. resulting differential equation motion integrated closed form. use proposed technique demonstrated with help illustrative example.
