Mechanical behaviours and engineering application of steel truss reinforced concrete transfer beam in tall buildings
A new type of steel reinforced concrete (SRC) transfer beam, the steel truss reinforced concrete (STRC) transfer beam, is developed and applied to a 100 m tall building in Guangzhou City to solve the difficulty of two built subways being buried under the building. Experimental studies on mechanical behaviours of STRC composite transfer beams were carried out, and the structural characteristics and economic characters of the transfer beam were introduced. Experimental investigations verify that the STRC transfer beam is of high limit bearing capacity, large rigidity and good ductility. Compared with normal reinforced concrete transfer beam, the limit bearing capacity of the STRC transfer beam can be enhanced 30–40%, and the rigidity can be improved 30–50%. In the STRC transfer beam, the strut‐and‐tie force transference mode is followed, the loads are mainly transferred by compressive diagonal SRC struts from the loading point and abutments, SRC struts and horizontal ties form a self‐balance system. The cost of material, fireproof and construction can be saved; more space for commercial function and convenient construction can be achieved by adopting STRC transfer beams.
