What do the values 710 and 1000 before and after the diagonal rod represent, and what is the difference between them? Seeking advice from experts
710 refers to the anchorage length value (l1) when the anchor bolt material is from the Q235 series； 1000 is the anchorage length value (l1) for anchor bolts made of the Q345 series material. When the seismic intensity is 7 or 8 degrees, its anchorage length should be multiplied by coefficients of 1.05 and 1.1 respectively.

For example, for M10 anchor bolts, when the designed tensile bearing capacity is 8.1 KN, the required anchorage length L1 in C30 concrete is 160; when the designed tensile bearing capacity is 10.4 KN, the required anchorage length L1 in C30 concrete is 210
