In order to establish the relationship between the measured dynamic response and the health status of long-span bridges,a double-layer model updating method for steel-concrete composite beam cable-stayed bridges is proposed.

Application of modified two-scale model for scattering from non-Gaussian sea surface;

Regarded steel bridge piers with box sections as numerical analysis object,using a modified two curved-surface model,the isotropic hardening model and kinematic hardening model,the hysteretic behaviors of steel bridge piers under positive and negative cyclic load were analyzed.

The current major application fields of satellite positioning some of tropospheric refraction correction model are introduced.

A new correction model for the target deviation is deduced when the optical axis is not parallel to the collimating axis, and the coordinates of the camera projection center in measuring coordinate systems are calculated in conditions of the mismatching between the optical center and the theodolite rotation center by using the object focus optical system as the projective center of camera system.

A profit distribution correction model for EPC engineering supply chain based on Shapley value was proposed which makes the profit distribution more reasonable.

Study on structure finite element model updating based on response surface methodology;

Comparative research on methods of dynamic model updating of structure;

Application of genetic algorithm on structural finite element model updating;

Study on the ecological carrying capacity in mining city based on the modified model of ecological footprint;

A modified model in this work was presented based on the entropic free-volume model which was proposed by Elbro atc.

The modified model can sufficiently reflect the distributed parameter characteristic of thermal systems, and can also apply to research on both full scale real time simulation training system and control system simulation of power plant.
