In this paper, a computationally effective strategy to obtain multioverlapping controllers via the Inclusion Principle is applied to design discrete-time state-feedback multioverlapping LQR controllers for seismic protection of tall buildings. To compute the corresponding control actions, the proposed semidecentralized controllers only require state information from neighboring stories. This pa...

Usually lifeline systems, such as water distribution network and gas supply network, cover large areas. For these systems, network topology design based on seismic reliability provides a good way to design new systems and update old ones. In this paper, a topology optimization model for lifeline networks is established. The aim of the model is to find the least-cost network topology while its s...

The design and analysis of seismically excited structural control systems should be based on the best available knowledge and information instead of the simplest available model when handling uncertainties in the civil structural system. Therefore, seismic structural control system is developed using fuzzy logic due to its capacity to formalize approximate reasoning processes, i.e., a knowledge...

Information can be conveyed as visual, tactile, vocal, olfactory or seismic signals (e.g. 5, 7, 9, 10). Different signalling modalities are present in different species, depending upon their sensory capacity and the environment where they evolved (1). For example, in a noisy environment visual display can have higher importance, while in nocturnal animals, animals that live in an environment wi...
