Notes:
In ultimate asseismic design of ductile frame structures, plastic deformation and plastichinge are generally permitted, and some preferred failure modes are often selected. It is animportant problem that whether the designed structure collapses according to the designed failuremode, because of the large uncertainties included in external loads and member strength. In thispaper, an identification procedure of failure modes for frame structures is developed, and the likelycollapse modes of frame structures under uncertain load and member strength are investigatedunder assumption of normal distributed and non-normal distributed external loads and memberstrength. It is found that the occurrence order of likely collapse mode is much influenced by thedistribution of the random variables. The occurrence order of collapse modes for column overdesigned structures are investigated and it is found that the increase of column over-design factorcan effectively avoid the story collapse mode in probabilistic means
