摘要
初始扭转叶片(梁)最早于航空、机械工程中有着广泛的应用。根据初始扭转叶片模型提出建筑结构工程中出现的1阶初始扭转梁概念,对目前国内外初始扭转叶片(梁)的研究概况进行综合阐述,对初始扭转梁的静力、振动和屈曲力学性能的研究现状进行概括并指出相应研究的不足之处,提出对初始扭转梁力学性能、可靠的力学分析模型和计算理论进行研究将具有非常重要的实际意义。
Pre-twisted blade or beam has an extensive application in the aviation and mechanical engineering firstly. It is put forward concept of first-order pre-twisted beam according to the model of pre-twisted blade in the building structure engineering. It is expounded the researches on the pre-twisted blade （beam） both at home and abroad. It is also summarized the state-of-art of its static force, vibration and buckling performance; and is pointed out its defects. It is finally carried out researches on mechanical behavior, reliable analytic model and calculation theories of the pre-twisted beam, which has important practical significance.
