- Abstract:
- To verify most of the numerical and analytical developments in the structural and earthquake engineering techniques, experimental methods have been considered by many researchers. For instance, numerical simulations in structural health monitoring, structural control and energy dissipation systems need to be verified and compared with experimental results. Consequently, research organizations spend substantial budgets on assessing and updating these experimental methods. Many of these experimental tests are essentially conducted on the benchmark structures with specific technical characteristics; these properties should not be changed after each experiment. Therefore, the tests on these structures have to be limited to elastic stage.
In this study, a benchmark structure is designed and manufactured using replaceable reduced beam section connection. By using this connection, the structure can be also used in nonlinear tests. In addition, to reduce manufacturing costs and afford limitations of shaking table, scaling technique by quarter-scale of benchmark structure is used. The benchmark structure has four stories with two bays at the moment frame and one bay at braced frame. Thirty eight RRBS connections are used in the whole structure. Three test specimens were prepared and two cyclic loads along with one monotonic load were applied to each test specimen under displacement control conditions. The moment–rotation hysteresis loops for all the test cases demonstrate the ability of connection in tolerating rotation till fourteen percent of radian. Finite element models are also verified by results of experimental tests. Furthermore, the ability of recovering and rehabilitating connections and rebuilding the structure after the various tests with very low cost, is one of the most important advantages of this new connection. It is believed that the construction of this benchmark structure will provide an appropriate situation for applied research at the edge of knowledge - Keywords:
