Study on mechanical properties of new wall-beam joints of prefabricated concrete structures
The flexible connection of prefabricated concrete structures usually has a fast and simple joint connection,but the mechanical properties of the joints,such as mechanical behavior and failure mode,need to be determined by experimental research.To study the mechanical properties of the new wall-beam joint in prefabricated concrete structures,a test is conducted to investigate the load-bearing performance of the joint,and finite element analysis is conducted to study the stress levels,failure modes,crack propagation,and other related characteristics of the joint.The study shows that the experimental results agree well with the finite element simulation.The new joint has the ability to resist torsional deformation and conforms to the principle of ductile design.The joint part of the embedded part and the concrete is prone to cracking,so it can be considered to strengthen the part appropriately to ensure the overall working performance.The lower part of L-shaped beam is prone to cracking due to tension.Attention should be paid to strengthening this part during the design process.
