一束形似变截面圆拱的构造图式方法及其规律

跨度L以30M为模数,当矢高f=L/6,跨中截面高度h=L/60时,所构成的一系列不同跨度的变截面园拱,其构图有一定的规律性,形成一束具有相同特征的形似构造图形。该构造图式方法,从理论上导出了此种系列任一符合上述要求之变截面圆拱的尺寸,并决定了其形状,可为喜好变截面圆拱这种结构形式的设计者提供出一套确定其建筑结构外形尺寸的定性设计及制图的方法。

A Number of Constructions Drawing Method and Their Rule that are Similar Like Variable Section Arch

Take span 30M (dimension: 3000mm) as modulus, when the height f=L/6, the section height of the span h=L/60, forms a series of variable section arch of different span, its construction drawings has certain rule, has formed a series of similar construction drawing of same property. The method of this construction drawing, from the theory has got the dimension of the variable section arch that complies with above requirement, and decides the shape. This has provided the designer that like the variable section arch construction a set of design and making drawing method for building outside dimension.
