Abstract

Rarely are structures designed such that they suffer no damage at all when subjected to a strong earthquake. Types of damage may include inelastic behaviour and even complete failure of a connection. Current finite element codes can predict the damage due to material behavior in the inelastic range, but it is difficult to properly analyse a structure which has a fracture type (e.g. connection) of failure. To bring the fields of finite element analysis and numerical simulation closer together, a finite element fragmentation algorithm is applied to this problem. This algorithm allows element fragmentation if a pre-determined "failure threshold" is reached. Due to the large deflections which possibly may occur an updated co-rotational approach is also incorporated into the code. Example problems show the capabilities of the code to analyse and simulate complete structural failure due to seismic excitation.
