| 要旨 | 1. INTRODUCTION Since demand for structures recently requires very complicated performance, only one type of structures, for instance, steel structure or reinforced concrete structure, may not able to meet the requirement of structures. The structural system, therefore, trends to be formed as a system of mixed structures. This system leads to the unavoidable connection joints of different types of structures, which is one of the problems arising in structural design method. One of these typical connection joints is the joint between the member in which structural steel plate is employed and the members in which reinforcing bars is utilized such as the connection joints between open-sandwich member and reinforced concrete member. Due to simplicity and flexibility in construction method, lapped splice connection is considered as a possible approach to treat this kind of connection joint. The way of splicing is to overlap between reinforcing bar and steel plate with welded rib and to make concrete responsible for flow of force in lapped splice. With the aim to develop the design method for this type of connection joint, performance of lapped splice between deformed bar and steel plate designated as “ composite lapped splice ” was investigated in this study. 5. CONCLUSION 1) Connection joint between deformed bars and steel plate in concrete medium can be treated as lapped splice connection. The formula for capacity of composite lapped splice was proposed. 2) The capacity of composite lapped splice is less than the capacity of ordinary lapped splice splice and anchorage because of difference in dimensional mechanism. Its effect can be practically considered by introducing constant reduction factor. 3) Effect of bottom covering on the capacity of composite lapped splice is less significant than in the case of ordinary lapped splice because steel plate and rib can behave as transverse reinforcement. |
