3This paper investigates the performance of a novel semi-active damping device at mitigating non-4 simultaneous multi-hazard loads. The device, termed modified friction device (MFD), has been previously 5 proposed by the authors. It consists of a variable friction system based on automotive drum brake technol-6 ogy. The device has been demonstrated in a laboratory environment, and its dynamic behavior modeled. 11show that the semi-active control cases outperforms all of the other cases for the vast majority of hazards 12 and performance indices, provided that the right control weights are utilized.

“…This is expected to be particularly important for the design of super tall timber buildings due to the lightness of typical timber construction. Concrete-framed buildings have a typical bulk density of 300 kg/m 3 (Yang et al, 2004). Steel buildings, including the concrete decking that often makes up the greater part of their mass, have a typical bulk density of 160 kg/m 3 (Huang et al, 2007).…”

This briefing presents some of the early findings of the super tall timber project, an innovative research and design project exploring the potential of engineered timber as a structural material in the construction of tall buildings. The project brings researchers together with practising engineers and architects in a process that combines design-led research with research-led design in a constructive feedback loop, providing a new model for addressing the fundamental challenges of designing with a new structural material. The first result of this project is a concept design for a 300 m tall timber building sited in London.

“…However, the relative merits of these active and semiactive controllers, as applied to base-isolated structures, has not been investigated by careful comparison on a well-defined benchmark problem. Recently well-defined analytical benchmark problems [16][17][18][19][20][21] have been developed for studying response control strategies for building and bridge structures subjected to seismic and wind excitation, by broad consensus effort of the ASCE structural control committee. The goal of this effort was to develop benchmark models to provide systematic and standardized means by which competing control strategies, including devices, algorithms, sensors, etc.…”

“…Carefully defined analytical benchmark problems are an excellent alternative to expensive experimental benchmark test structures. Due to the effectiveness of the fixed-base building benchmark effort [17][18][19][20] the ASCE structural control committee voted to develop a new smart baseisolated benchmark problem. Narasimhan et al [22][23][24][25] and Nagarajaiah et al [26,27] have developed the smart base-isolated benchmark problem, based on input from the ASCE structural control committee, with the capability to model different kinds of base isolation systems [39][40][41]: linear elastomeric systems with low damping or supplemental high damping; frictional systems; bilinear or nonlinear elastomeric systems or any combination thereof.…”

SUMMARYSample controllers for a three-dimensional smart base-isolated building benchmark problem with linear and frictional isolation system are presented in this paper. A Kalman filter is used to estimate the states based on absolute acceleration measurements. Input filters are used to better inform the controller of the spectral content of the earthquake excitations. A reduced order control-oriented model of the benchmark structure with a linear isolation system is developed. A H 2 /linear quadratic Gaussian controller is presented for the active case; additionally, a clipped optimal controller is presented for the semiactive case. A preliminary 'skyhook' semiactive controller is also presented for the benchmark problem. Magnetorheological fluid dampers are used for control in the semiactive case and ideal actuators are used for control in the active case. The focus of this phase I study is on the linear isolation system only. Computed results for the passive, semiactive, and active cases are presented. Detailed comparisons of benchmark performance indices for base-isolated structures with a nominal linear isolation system, with and without control, for a set of strong near-field earthquakes are presented. The modeling and sample control designs demonstrated in this paper can be used to form the basis for studying a wide variety of active and semiactive control strategies}to be developed by the participants in the benchmark study}for linear base-isolated buildings.
