Non-linear Analysis Bearing Performance Of The Cast-in-situ Concrete Light Pipe Column Wallboard

We embed hollow tubes into the basement wallboard according to certain rules to form the cast-in-situ concrete light pipe column wallboard. Based on the existing research, basement wallboard with hollow pipes embedded will effectively reduce the temperature stress of the wallboard and control the development of cracks. This essay will further study and analyze mechanical performances of the cast-in-situ concrete light pipe column wallboard on the foundation of experimental researches in hand. The main work is as follows:1. This essay will employ the yield line theory to establish the bearing capacity formulas. First, it will come up with geometrical shapes of the yield line about the castin-situ concrete light pipe column wallboard on the consideration of boundary conditions, load patterns, crack developments and so on. Then it will apply the Virtual Work Principle to calculate the bearing capacity of the cast-in-situ concrete light pipe column wallboard.2. The deflection and internal forces of the cast-in-situ concrete light pipe column wallboard with three sides simply supported and one side fixed is calculated by using Small Deflection Theory of the thin plate under triangular load distribution and even load distribution. Relevant calculation indexes of the deflection and internal forces can be formed and utilized to practical engineering design.3. This essay will study the non-linear behaviors of the cast-in-situ concrete light pipe column wallboard by using the ABAQUS Finite Element Analysis Software. Also, the software will be used to analyze how volumetric void ratio, pipe length, load patterns, boundary conditions, axial compression ratio and loading position affect the bearing capacity of the cast-in-situ concrete light pipe column wallboard. At last, it will bring forward design suggestions and provide technical parameters for a wider utilization of the cast-in-situ concrete light pipe column wallboard.
