Within this contributio n,the general po ssibilities of modeling building collapse initiated by controlle d explosion/ blast with expli c it finite elem ent analys is are discu s sed.It has bee n show n,that the begin -ning of a buil d ing collap s e,describ ed by a few rigi d body like part s ,conne cted by local zones of ac-cumul a ted da mage is very well ca ptured by the pres ented finite element mode l.In the course of the collapse pr ocess,due to the in crea se of complexity of the kinem atical system,the simulation re sults differ c u mulatively,caused by the rather s implifie d descri p tion of the com p lex material beh avior ofreinfo rced concrete.In the pre s ente d ca se,espe cially the modelin g of material failure by el ement ero-sion at specifi c criter ia is m a inly respon sible for the unphysi calchange in kine ma tics,becau se in real-ity,debris ha s still influence on the structure,whic h does no t exist in the pres ented simul a tion .Furtherinvestigations with more suitable stru ct ural and mate rial m odel s and the deve lopment of b e tter fitting failure criteria for reinforce d con c rete are fields of furt her investigations.
