“…In the analysis of WRD, wind vibration experiment is the most necessary. Especially for the situation of HRB, the structure needs to reduce its own vibration amplitude and frequency based on bearing wind load, so as to cater to the good frequency of wind load and prevent structural resonance [8]. At this time, it is necessary to conduct a model wind vibration experiment for a given building and its structure based on theoretical calculation.…”

With the rapid development of building level and construction technology, high-rise buildings have been adopted more and more, thus becoming an important place for people to work and live. Because of the high height of high-rise buildings, wind load becomes the main resultant force type of high-rise building. However, wind load has great randomness and unpredictability, which has great influence on the stability of high-rise building. This paper first analyses the main characteristics of wind load borne by tall buildings. Then, the common methods of wind-resistant design of high-rise building are summarized in detail. It also points out the existing problems and deficiencies in wind resistance design of high-rise buildings and the countermeasures and suggestions of wind resistance design of high-rise structures. Finally, according to the current research status and existing problems, the future development of wind resistance design is prospected. Results can provide some references for wind resistance design and research of high-rise buildings.

“…By simulating the particular vibration environment that products will exposed to in use, transform, and storage, the weakness of design can be early found and the information for correcting design can be obtained in time. 2 The vibration simulation is normally produced by hydraulic actuator (cylinder or motor) or electric motor to generate different kinds of vibration forces. 3 Compared with other types of drives, hydraulic drive has many distinct advantages, such as high power mass ratio and stiffness, fast response, high control precision, compactness, and high payload capability.…”

A hydraulic composite actuator is developed for vibration simulation. The hydraulic scheme and control principle are introduced and an open-closed-loop iterative learning control method is proposed for control issue. A special composite cylinder controlled by servo valve and proportional relief valve is designed to generate static force with large amplitude and dynamic force with small amplitude but high frequency. The control subsystem for dynamic force is a zero-type system with very high open-loop gain and uncertainty of parameters; therefore, an open-closed-loop proportional-derivative-type iterative learning control scheme is designed to solve this challenging control issue. A principle prototype of this hydraulic has been developed, and the experiments have been designed for this actuator. Different control methods are experimented for verification and comparison, and experiment results have verified practical applicability of this actuator and the superiority of control scheme.

In this study, the nonlinear vibration model of structure with cross support is established. The conventional structure without cross support is linear and easy to be investigated. Unfortunately, its dynamic stability and vibration due to earthquake excitation are usually not acceptable. For suppressing the structural vibration the cross support composed of the elastic connecting bar and damper is considered here. This is a passive control design. Beside, due to the supporting arrangement, the mathematical model of the structure is highly nonlinear. In this study, the analytical solution for this system is derived. Further, the effects of control parameters on the vibration response are investigated.
