Alternatively, optimum forces in the devices can be achieved by semi-active control, where the structure self-adapts to the earthquake. Both solutions are expensive: the first requires hundreds of non-linear response simulations in the design stage; the second needs a system of sensors, controllers and electromechanical devices. Presented here is a new Self-Adaptive Optimisation Approach (SAOA ...

Passive building design - Designing Buildings Wiki

Semi-active control systems: A semi-active control system may be defined as a system which typically requires a small external power source for operation (e.g. a battery) and utilizes the motion of the structure to develop the control forces, the magnitude of which can be adjusted by the external power source. Control forces are developed based on feedback from sensors that measure the ...
