Wind Induced Vibration Response

As a new long-span double-arch-support steel structure system is applied to a stadium, it is necessary to study the wind-induced vibration response of the roof structure to meet the need of design. The modal analysis and the response analyses which include static wind response and wind-induced vibration response are calculated by ANSYS. The results show that the natural vibration frequency of structure is intensive (0.93 Hz~4.2 Hz). The most unfavorable wind direction angle of 135o is selected to study the wind-induced vibration response. And the wind-induced vibration coefficient calculated is satisfactory when compared with the wind tunnel test. It can be seen that it is feasible to use the stochastic simulation analysis method of wind-induced vibration response to get the wind-induced vibration coefficient.

Abstract Gauge blocks are one of the most widespread measurement standards (etalons) in dimensional metrology laboratories. Among all its properties, it is worth highlighting the importance of dimensional stability. This property allows to classify these measuring instruments in quality grades. Although the gauge blocks should be dimensionally stable, it can be observed that there is a drift that can be observed when the calibration history is revised. In this document, authors present a statistical method for the estimation of the dimensional stability of gauge blocks using the calibration history of samples from the main manufacturers. In addition, all the samples have been subjected to metallographic analysis to evaluate the structure.

In this study, on airport terminal building design, passing long span beams and the concept of biomimesis have been the design criteria; the use of a steel structure has been examined for supporting the design form. In the airport terminal building, steel roof types in smooth surfaced, single curved-arciform, and double-curved wave forms have been designed. The three different types of steel frame roof model have been designed with the forms frequently used within the scope of the biomimesis concept and provide a covering shaped like a bird's nest, bird wing and bubble. Dynamic analysis of the three different roof forms is according to the first-degree seismic zone and Z4 local ground class. As a result, in the long-span design criterion, the aesthetics and function influence each other and change the building's behaviour.

Steel Roof

The long-span spatial steel structure takes its complex construction process because of its features, such as large scale, wide range, and long cycle duration. Simultaneously, the structural construction process can not only affect the shaping of long-span spatial structure, but also produce a great effect to structural final force state, which makes the construction monitoring of long-span spatial steel structure necessary. The most important construction parts for Shenzhen Bay Stadium steel roof are unloading process and closure process. Considering the structure complexity in the construction phase, a structural health monitoring system was installed, which began to be built in early 2010 and contained two phases: construction monitoring and operation monitoring. In this paper, the temperatures and displacements monitoring in construction phase are firstly described in detail. The monitoring data of temperature and displacement measured in unloading and closure phases are then analyzed, respectively. According to these monitoring data, the comprehensive understanding for the structural performances in construction phase is shown and discussed, which can provide a reference of construction monitoring for the related projects.

Due to the applicable installation overhang large span, small mass, flexible characteristic, and small damp, the cable-stayed steel structure awning (CSSSA) could easily result in vibration with the wind load. The main factor is the turbulence wind and wind-rain induced vibration. Combining the structural dynamic theory, and considering the characteristic of the CSSSA, a motion differential equation is set up considering the wind-rain induced vibration, analysis cable-stayed stability under wind-rain induced vibration effect, and compare with the existing engineering result. Hope to provide some reference for similar designs.
