Abstract: The concept of an active structure is presented in this paper. An active structure is defined as one consisting of two types of load‐resisting members: the static or passive members, and the dynamic or active members. Their ...

Abstract: The current highway bridge design codes treat the dynamic effect of traffic loads by applying an empirical amplification factor, called the “impact factor,” which is a function of span length only and has little theoretical ...

Abstract: This work presents a methodology for the shape control of structures undergoing inelastic deformations through the use of an active pulse/force system. Large flexible structures such as tall buildings, long bridges, and ...

Abstract: This work investigates the response of secondary systems attached to a base‐isolated, six‐story model structure that is subjected to base motions. The secondary systems are modeled by cantilevered, inverted pendulums. They ...
