Study on LQR control algorithm using superelement model
The conventional linear quadratic regulator (LQR) control algorithm is one of the most popular active control algorithms. One important issue for LQR control algorithm is the reduction of structure’s degrees o...

Experimental and numerical analysis of submerged floating tunnel
As a new type of structure which has never been built, submerged floating tunnel was studied mainly by numerical simulations. To further study the seismic response of a submerged floating tunnel, the first mod...

Dynamic analysis of subway station subjected to internal blast loading
The study was motivated by the fact that explosion inside the subway structure may not only cause direct life loss, but also damage the subway structure and lead to further loss of lives and properties. The pr...

Statistical damage model for quasi-brittle materials under uniaxial tension
Based on the parallel bar system, combining with the synergetic method, the catastrophe theory and the acoustic emission test, a new motivated statistical damage model for quasi-brittle solid was developed. Ta...
