This steel bar should be HTRB600, right? The shape of HTRB600 high-strength steel bar is the same as that of ordinary hot-rolled ribbed steel bar. In the plan atlas16g1kloc-0/,the maximum reinforcement is HRB500, and the reinforcement above HTRB600 has no anchorage length. ? Code for Design of Concrete Structures (GB500 10) stipulates the basic anchorage length lab, anchorage length la and seismic anchorage length laE of HTRB600 high-strength steel bars, which are related to the tensile strength of steel bars and concrete. Please refer to the following figure:
