超大跨径桥梁或强风、强震区的大跨径桥梁,其的静力、动力响应对桥梁结构设计往往成为控制因素,运用缓冲器、阻尼器和弹性连接等附加装置能有效地改善大跨径桥梁结构受力。在苏通大桥结构体系研究的一些思路和国内外有关资料的基础上,将十多年来应用的一些装置从性能、特征参数和工程应用理念等方面加以较系统地叙述,希望为我国桥梁在这方面的应用提供一些有益的帮助。 相似文献

Based on the data collected from a large-scale survey research of 1622 consumers, the present paper develops a disaggregate, compensatory choice model to collectively examine the impact of under-examined factors on consumer car type choice behaviour. All existing econometric forecasting models of vehicle type choice in the literature have so far considered objective measures as determinants of vehicle type choice. The proposed choice model considers 12 car-type alternatives and is successively extended to allow for choice probability distortions resulting from individual heterogeneity across a set of 30 variables, related to objective, behavioural and psychographic consumer characteristics. The results provide clear evidence that variables such as purpose of car use, prepurchase information source used, consumer’s proneness towards buying an ecological car, consumer’s involvement with cars, and consumer’s attachment to cars, significantly affect car type choice. The results yield important implications for manufacturers, transportation planners and researchers. 相似文献
