Computation and analysis are performed at different axial compression ratio on flexural and shear strength of CSRC columns with four different steel ratio and N—M curves were drawn and the strength is compared with RC columns.

The composite column with concrete filled steel tube inside can provide great advantages over either pure steel or reinforced concrete members, as a kind of composite component, it has been increasedly used over the recent years.

Nonlinear numerical simulation on five core steel reinforced concrete columns(CSRC) using ANSYS program was carried out.

This article illustrates the design pattern and the node design characteristic of the tall frame-supported shear wall structure base steel reinforced concrete column,and propose the key question and the technical measure in design concerning project practice.

Based on the test data of 61 steel reinforced concrete columns,a model with 5 input layers,6 implicit layers and 1 output layer(5-6-1) is developed to analyze the influence of various parameters on displacement ductility by the principle of back propagation(BP) neural network.

The main technical problem of the construction technology of super high as-cast-finish steel reinforced concrete column is formwork construction.

Influence of steel placement eccentricity on bearing capacity of SRC columns

A calculation formula with a clear and definite physical meaning is derived for the limit value of the axial compressive ratio of SRC column,the result out of which is in agreement with the limit value of the axial compressive ratio of reinforced concrete column precscribed by "code for design of concrete structures".

Based on study of the experiment, The patterns and reasons of bonding failure of SRC columns are gived,the principle of shear resistance is ana- lyzed.
