【摘要】 利用虚功原理,通过对半跨荷载作用的圆弧拱结构力学模型的建立,取得破坏位置的简化计算方法,通过编程计算,求得其破坏位置大小,并与全跨荷载作用时的屈曲破坏位置作以比较和分析,其计算方法是精确和实用的。从而为其他形式拱结构屈曲破坏位置的分析提供了可靠的方法。更多还原

【Abstract】 Using the principle of virtual work,through the establishment of segmental arch structure mechanics model of semi-cross load function to obtain the simplification computational method of destroyed position.Through the programming computation and find the size of destroyed position,and compares and analyses the flexure destroyed position with the entire cross load function,its computational method is precise and practical,which provides the reliable method for other ached structure flexure for other flexure destroyed position.更多还原
