How to use steel drop in anchor and chemical bolts with each other

In terms of structural safety, the upper river basin friends dissected the thin layer, K2 = 2, K1 = 1.4 (for wind load index value), so k = 2 * 1.4 = 2.8. At this time, under the wind load, the probability of the structure reaching the compressive strength of failure is 1/1120, and the probability of people taking the wind load index value according to the 50-year design standard period is 2%, so the embedded parts of the people are connected . For wind loads, the damage rate is very low. Naturally, this is just a reference for everyone to perform quantitative analysis and understand probability. In fact, the entire process should be used. As the friends of the basin often say, the ultimate failure of the bolt to the compressive strength of the engineering concrete should be selected as the basis, and the tensile test should be conducted on the field as a certification. Total embedded parts or individual chemical bolts within the length of on-site welding or electric welding shall be standard. It is best to choose the whole)
