Progressive collapse analysis of reinforced concrete structure

U;~ event of local failure that occurred in structural system could lead to a disastrous incident.
What actually happen during the occurrence of collapse and what triggers the process could not

approach that is used to create this situation is by removing one of the critical supp,_;rt s!ruct.;;c:s
that hold the system as a whole. The model is first designed to work as a normal slru<:turc and

hold a section whether in the middle or at the structures end, it will a produce a condition that
replicate the state of local failure due the loss of the supporting member.

the load path of the structure can be observed and analyzed.
