Development of Equivalent Force Control Method for Pseudo- Dynamic and Real-time Substructure Tests
نویسندگان
چکیده
The equivalent force control (EFC) method replaces numerical iteration with a feedback control strategy to solve the nonlinear equations of motion in pseudodynamic and real-time substructure tests (RST) using an implicit integration method. The EFC method and its further development with an energy conserving integration method are presented in this paper. The effectiveness and accuracy of the EFC method are validated with quasi-static pseudo-dynamic tests of structures with buckling restrained braces and a reinforced concrete shear wall, and RST of structures with springs, buckling restrained braces, and an MR damper, respectively. It is shown that the EFC method can deliver excellent performance in all cases.

Evaluation of the SEAOC/UBC97 Provisions for the Tall Base-Isolated Structures
The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...

متن کاملModification of Equivalent Consumption Minimization Strategy for a Hybrid Electric Vehicle
Equivalent consumption minimization strategy (ECMS) is one of the main real-time control strategies for hybrid electric vehicles (HEVs). This paper proposes a method to modify this strategy. This modification reduces calculation time of ECMS and therefore, facilitates its application as the real-time controller. Dynamic programming (DP) method is employed to reach this aim. This method is appli...
متن کاملAnalysis and Preliminary Experimental Study on Central Difference Method for Real-time Substructure Testing
Central difference method (CDM) that is explicit for pseudo dynamic testing is also supposed to be explicit for real-time substructure testing (RST). However, to obtain correct velocity dependent restoring force of the physical substructure being tested, the target velocity is required to be calculated as well as displacement. The standard CDM provides only explicit target displacement but not ...
