LOAD-BEARING CAPACITY AND DESIGN METHOD OF EMBEDDED ELEMENTS.

In this paper, the load-bearing capacities of embedded elements under shear, tension combined with shear and bending combined with shear are systematically analyzed on the basis of test results of 340 test pieces from which a calculating model is put forward. The calculating formulas derived from the calculating model present a more clear conception and their calculated results are in good agreement with test results. The formulas are of high adaptability and simple and practical after simplification. This paper also presents a reduction factor of strength required for checking shock strength based on the test results of embedded elements under low period repeated loading.
