Design and research of reinforced concrete truss type transfer structure
A new type of reinforced concrete truss type transfer structure was proposed.Taking Panyu Tianhe City as an example,the advantages and disadvantages of truss type transfer,traditional beam type transfer,and steel truss transfer were elaborated,and the overall indicators and material consumption of these three transfer schemes were compared and analyzed.In addition to verifying the safety and revealing the stress mechanism under mid earthquake elasticity,the elastic-plastic damage of truss type transfer story components under large and super large earthquakes were also evaluated,and their yield mechanism were studied.Through three-dimensional finite element analysis of truss type transfer nodes,the connection reliability was verified,and corresponding node construction measures was proposed.The research results indicate that reinforced concrete truss type transfer structures have good mechanical performance,can expand building usage space,save engineering costs,facilitate construction,and achieve reasonable transfer of high-rise frame supported structures.
