A Theorical Study On Earthquake Resistant Control Of Double-layer Cylindrical Latticed Shells

The seismic response of lattice shells is complex subjected to earthquake. Because of large of work during controlling process, the computation for the response is difficult. The double-layer cylindrical lattice shell is researched with controlling theory in this paper. One end of the model of the double-layer cylindrical lattice shell in the paper is underpinned by rim, the other end is underpinned by rubber spring. We adopt half-active control at the model. We actualize real-time control with symbol control theory and optimization control theory, to reduce the seismic response of each nodal of the double-layer cylindrical lattice shells under earthquake. We also study the position of stiffness and damping implements.
