Due to the demand of manufacture technology, the main factory building of large-scale thermal power plant forms frame-bent structure with the integration of multistory frame and single bent construction. In view of the mechanical behavior complexity of the joints of main factory building structure, four typical SRC abnormal exterior joints were chosen to be carried out the experimental research based on large-scale thermal power plant SRC frame-dent structure sub-space modle test done by our research group. Through the pseudo-static test of SRC abnormal exterior joints, this paper describes the damage process of the joints, mainly studys on the failure mode of the SRC abnormal exterior joints, and analyses a variety of factors affecting seismic behavior of SRC abnormal exterior joints. Thus, it may provide some valuable ideas for seismic design of this kind of joints.

This paper focuses on the control problem of spring-connected inverted pendulum by variable universe adaptive fuzzy control that is proposed in [3, 5]. First, the mathematical model on the n -order spring-connected inverted pendulum is described and its controllability is verified when n = 3. Then, an efficient controller on the triple spring-connected inverted pendulum is designed by using variable universe adaptive fuzzy control theory. At last, the simulation is well shown in detail.

For a class of uncertain nonlinear systems, a design method of robust fuzzy control systems with the state estimators is developed in this paper. This design method guarantees each local closed-loop systems poles within a specified disc and steady-state variances to be less than a set of given upper bounds. T-S fuzzy models with uncertainties are used as the model for the uncertain nonlinear systems. A sufficient condition for the existence of such robust fuzzy controllers is derived using the linear matrix inequality approach. Based on this, solving procedures for the feedback gains and the estimator gains are given.

Power plant is a kind of critical infrastructure. The single span concrete frame-bent structure-which is called "single frame structure", is often used in main building because of the equipment layout optimized design. Kobe earthquake, Chi-Chi earthquake and Wenchuan earthquake show that the single span frames are easily damaged. So the "Code for seismic design of buildings" GB50011 and the electric industry codes make strict rules for the use of single frame structure. In order to distinguish the similarities and differences between the "single frame structure" in main power plant and conventional single-frame structure, a dynamic elastic-plastic time-history analysis is carried out based on the characteristics of the main building structure in power plant. The scope of application is given for this kind of structure and the design guide is specifically complied for engineering design.

The structure system of industrial buildings depends upon the production technology and operating requirements, so the complexity of the production technology always leads to a complex structure style. A vertical hybrid structure is formed to meet the technological requirements. Selecting a practical structure, choosing 1/4 substructure, imitating the boundary condition, and constructing a 1/8 scale model, a pseudo-dynamic test is conducted to study the seismic behavior of this structure. In the experiment the model is subjected to El Centro wave (1940 NS ) with the peak value of acceleration varying from 50 gal to 800 gal. The dynamic response of the structure is obtained in the test. The alteration of the natural frequency of vibration and the damping ratio, the hysteretic behavior and the failure mode of the model are analyzed. A formula to calculate the horizontal bearing capacity of the structure is suggested based on the results of the experiment. The research can provide basis to the seismic design methods of the structure.

Hybrid structure is a type of structure which is frequently used in high-rise buildings. In this paper, the distribution characteristics of the earthquake forces in the core wall and outer frame are centered around, which are two earthquake fortification lines in this structure system. The commonly used methods are summarized, which are adopted to intensify the first fortification line—the ductility of the core wall and to increase the second fortification line —the stiffness and ductility of the outer frame, and their advantages and disadvantages are analyzed respectively.
