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.

Study on the displacement ductility index of steel reinforced concrete columns;

The Finite Element Analysis on Hysteretic Characteristics of Steel Reinforced Concrete Columns;

The numerical calculation theory of the 3D temperature field is introduced,and based on the defini-tion of the thermal properties of steel and concrete under the elevated temperature,the 3D temperature field of steel reinforced concrete columns under fire is analyzed by the finite element analysis software ANSYS.
