The finite element modes of composite columns were built. The nonlinear analysis of the common steel column and the partial concrete encased steel composite columns were conducted. The load-displacement curves were getting. The strength of partial concrete encased steel Strengthened columns was much higher than the common steel column. Finally, Construction design suggestions and theory study of the type of partial concrete encased steel composite columns are advanced according to the results of analysis and computer simulation.

On basis of the data from tests, FE nonlinear analysis mode on the multi-planar CHS KK-joints with in-plane gap and out-of-plane overlap (KK-OPOv) was advanced and validated in terms of failure mode, ultimate bearing capacity and etc. And the adaptability is reasonable. Moreover, FE nonlinear analysis for the joint on the typical load-displacement curve, failure behavior, failure mechanism and etc was conducted. The study suggests that the multi-planar KK-OPOv joints appear mainly in the CLD1 failure mode; at the time of failure, the tube wall deformations on the chords of multi-planar KK-OPOv joints and the corresponding planar K-Gap joints are coincide with each other basically. Both of these two types of joints are of a same failure mechanism; the multi-planar parameter ζt influences, to a certain extent, the ultimate bearing capacity on joints. That is, as the overlapping ratio of the out-of-plane braces is higher (namely, the absolute value of ζt increases), the ultimate bearing capacity of the joints decreases.

Deem test results from the low reversed cyclic loading quasi-static test with 2 RC columns as the basic information of secant stiffness damage of the reference column and take use of the TMS instrument in the test to artificially make the damage percentage of secant stiffness of the RC column as 33%, 50% and 66%, 6 damaged columns in total; reinforce the 6 damaged columns and 2 undamaged ones under the same conditions with AFL, through quasi-static contrast test. Test results show that it is able to effectively boost horizontal ultimate bearing capacity and ductility deformability of the RC columns with AFL for reinforcement; besides, there is a linear function relationship between horizontal ultimate bearing capacity, target ductility factor, and damage percentage of secant stiffness.
