Abstract
The finite element software ANSYS is used to calculate the ultimate bearing capacity of ordinary beam and circular hole beam, and the results are compared with the test values made by predecessors. The value of shear transfer coefficient between cracks of reinforced concrete beam with circular hole in the abdomen in ANSYS finite element simulation is summarized. The coefficient is used to simulate the circular hole beam strengthened by steel sleeve, and it is pointed out that the steel tube is used to reinforce the circular hole beam The effect of tube reinforcement on the bearing capacity of circular hole beam is not obvious.
Highlights
In the construction of reinforced concrete buildings, openings are often needed in the beams due to the installation of ventilation, air conditioning, and water pipes
Liu Xiaochun [3], Wang Peng [4], Yang Yuhua [6] and Cai Jian [7] carried out a large number of experimental studies, and summarized the influence of various factors on composite beams
Liu Shizhong [8], Jiang Jiaohe [9], Wang Dongsheng [10], Li Yiqiang [11], Luo ruden [12], Zhu Mingqiao [13] etc. simulated and analyzed the supported concrete beam and the concrete beam with supported square hole in the abdominal wall by using the ANSYS finite element simulation software, which verified the effectiveness of the ANSYS analysis, and discussed these problems, such as the finite element model, the selection of constitutive relations and parameters, and the convergence of solutions
Summary
In the construction of reinforced concrete buildings, openings are often needed in the beams due to the installation of ventilation, air conditioning, and water pipes. Wang Xinling et al [2] carried out experimental analysis on the supported beam with opening in the middle span under concentrated load, and obtained that the bearing capacity of the continuous beam is related to the area and location of the opening, and gave the limiting conditions of the opening and design suggestions. Liu Xiaochun [3], Wang Peng [4], Yang Yuhua [6] and Cai Jian [7] carried out a large number of experimental studies, and summarized the influence of various factors on composite beams. Simulated and analyzed the supported concrete beam and the concrete beam with supported square hole in the abdominal wall by using the ANSYS finite element simulation software, which verified the effectiveness of the ANSYS analysis, and discussed these problems, such as the finite element model, the selection of constitutive relations and parameters, and the convergence of solutions.
