作者： gu ming State Key Laboratory of Disaster Reduction in Civil Engineering Tongji UniversityShanghai 200092China

In recent years many long-span bridges have been or are being constructed in the world, especially in China. Wind loads and responses are the key factors for their structural design. This paper introduces some important achievements of wind-resistant studies of the author's research team on long-span bridges. First, new concepts and identification methods of aerodynamic derivatives and aerodynamic admittances were proposed. Then mechanical and aerodynamic control strategies and methods of wind-induced vibrations of long-span bridges were the great concerned problems, and valuable achievements were presented. Especially, great efforts which have been theoretically and experimentally made on rain-wind induced vibration of cables of cable-stayed bridges were described. Finally, some new progresses in computation wind engineering were introduced, and a new method for simulating an equilibrium boundary layer was put forward as well.

A Novel Onboard-gateway-based Mechanism to Improve TCP Performance in Aeronautical Satellite Networks

引用

Chinese Journal of Aeronautics 2007年第3期20卷 260-265页

作者： gu ming ZHANG Jun School of Electronics and lnformation Engineering Beijing University of Aeronautics and Astronautics Beijing 100083 China

The IP-based networks on aircraft serve to support Intemet services via satellites. However, in aeronautical satellite hybrid networks, the TCP protocol performance often deteriorates due to improper decreases and slow recovery of the congestion window. This paper proposes a window size determination and notification mechanism, onboard-gateway-based mechanism （OGBM）, which is based on the onboard gateway in the networks on aircraft. A cross-layer approach is adopted by the onboard gateway to obtain the satellite link bandwidth information. And then, by the gateway, through changing the receiver＇s advertised window field in ACK packets, TCP sources are notified of the window size of each TCP source calculated on the ground of bandwidth delay product and flow numbers. The mechanism is able to avoid improper changes of TCP window and serve multiple users. Simulation results show that the mechanism with the fairness index close to l improves TCP performance in aeronautical satellite networks.

武汉市碳酸盐岩天兴洲条带,发育一套巨厚层砂化白云岩,其岩体力学参数取值,目前尚无相关经验或建议。基于Hoek-Brown(简称H-B)准则及其Mohr-Coulomb(简称M-C)线性转换理论,归纳总结前人研究成果,在试验数据的基础上,研究了砂化白云岩的H-B准则参数,提出一种基于静止侧压力系数k_(1)的最大围压上限σ_(3max)简化取值方法,估算其岩体力学参数并给出了取值建议。结果表明:基于k_(1)的σ_(3m)_(ax)简化取值方法,合理缩减了围压σ_(3)的取值区间,提高了计算精度;砂化白云岩的地质强度指数GSI与无侧限抗压强度σ_(ci)呈良好的线性关系,结合其砂化程度在岩体块度上的贴切表现,制作了针对砂化白云岩的改进GSI建议值表;岩体材料参数m_(i)的大小主要受控于岩石种类及细观颗粒的粗糙程度,其取值区间跨度小且对岩体力学参数影响较小,取用m_(i)=9;通过H-B准则与M-C准则的线性转换,建立了σ_(ci)与岩体抗剪强度之间的计算关系;各试验值、拟合值及理论计算值之间关系自洽、结果合理,有效解决了极破碎白云岩岩体力学参数的取值问题。上述基础性工作对H-B准则的应用起到了有益的补充,对武汉市类似岩层的岩体力学参数取值方法研究及运用具有重要借鉴意义。

Across-wind loads and effects of super-tall buildings and structures

引用

Science China(Technological Sciences) 2011年第10期54卷 2531-2541页

作者： gu ming QUAN Yong State Key Laboratory of Disaster Reduction in Civil Engineering Tongji University Shanghai 200092 China

Across-wind loads and effects have become increasingly important factors in the structural design of super-tall buildings and structures with increasing height. Across-wind loads and effects of tall buildings and structures are believed to be excited by inflow turbulence, wake, and inflow-structure interaction, which are very complicated. Although researchers have been focusing on the problem for over 30 years, the database of across-wind loads and effects and the computation methods of equivalent static wind loads have not yet been developed, most countries having no related rules in the load codes. Research results on the across-wind effects of tall buildings and structures mainly involve the determination of across-wind aerodynamic forces and across-wind aerodynamic damping, development of their databases, theoretical methods of equivalent static wind loads, and so on. In this paper we first review the current research on across-wind loads and effects of super-tall buildings and structures both at home and abroad. Then we present the results of our study. Finally, we illustrate a case study in which our research results are applied to a typical super-tall structure.

Grouping response method for equivalent static wind loads based on a modified LRC method

引用

Earthquake Engineering and Engineering Vibration 2012年第1期11卷 107-119页

作者： Zhou Xuanyi gu ming Li Gang State Key Laboratory of Disaster Reduction in Civil Engineering Tongji UniversityShanghai 200092China

Wind loading is one of the most important loads for controlling the design of large-span roof structures. Equivalent static wind loads, which can generally aim at determining a specific response, are widely used by structural designers. A method for equivalent static wind loads applicable to multi-responses is proposed in this paper. A modified load- response-correlation （LRC） method corresponding to a particular peak response is presented, and the similarity algorithm implemented for the group response is described. The main idea of the algorithm is that two responses can be put into one group if the value of one response is close to that of the other response, when the structure is subjected to equivalent static wind loads aiming at the other response. Based on the modified LRC, the grouping response method is put forward to construct equivalent static wind loading. This technique can simultaneously reproduce peak responses for some grouped responses. To verify its computational accuracy, the method is applied to an actual large-span roof structure. Calculation results show that when the similarity of responses in the same group is high, equivalent static wind loads with high accuracy and reasonable magnitude of equivalent static wind distribution can be achieved.
