But the current specification GB50018-2002 does not consider the effect of lip inclination, hence, it cannot be effectively used in designing inclined lipped Z-section purlins.

而现行冷弯型钢设计规范GB50018-2002采用有效截面法计算受弯构件的屈曲荷载并没有考虑卷边角度的影响，不能合理的进行斜卷边Z型檩条的屈曲荷载设计。

Based on the results of the study, the angle of the lip stiffener has great effects on the buckling coefficients of inclined lipped flange, and cannot be neglected in calculating buckling strengths of inclined lipped Z-section purlins.

用规范中提供的截面来验证该公式的合理性，结果表明：当卷边角度在40°—90°的范围内时，误差在3％以内，可以满足实际设计要求，并能够推广应用于计算常用斜卷边Z形檩条的翼缘屈曲系数。

Constant load stress: Constant load refers to the structure of the shelf itself, self-respect, and the Housing Connection C-shaped steel frames, purlins, the Housing frame, roof, panel weight.

受力恒荷载：恒荷载指货架本身结构的自重，连接C型钢和房架、檩条、房架、屋面板、墙板的重量。

Circular steel arch es are distributed along the short span of the shell as the main load-bearing component,while steel tubes of rectangular section are distributed as purlins between the arches along the long span.

为满足建筑设计简洁通透的要求，该工程采用了沿椭球面短轴方向布置圆形钢拱结构为主要承载构件、拱间沿长轴方向布置矩形钢管作为檩条的结构方案。

Circular steel arches are distributed along the short span of the shell as the main load-bearing component, while steel tubes of rectangular section are distributed as purlins between the arches along the long span.

为满足建筑设计简洁通透的要求，该工程采用了沿椭球面短轴方向布置圆形钢拱结构为主要承载构件、拱间沿长轴方向布置矩形钢管作为擦条的结构方案。

In the aspect of roof conformations, the purlins of roofs and material , Chi-Shan has the characteristic of " Shuang-ying-zai", and its material almost bamboo or mixing bamboo or wood .

在屋顶构造、桁檩配置与材料使用差异方面，旗山具有「双楹仔」配置特色，材料多为竹材或木竹混用，屋顶形式多为硬山式，细部运用红砖组砌产生的变化较多；美浓则坚持单根配置而无「双楹仔」，但中脊处有「双栋梁」的特色，且屋顶多为悬山式，桁檩直接突出山墙面的做法较朴实。

I sometimes dream of a larger and more populous house, standing in a golden age, of enduring materials, and without gingerbread work, which shall still consist of only one room, a vast, rude,substantial, primitive hall, without ceiling or plastering, with bare rafters and purlins supporting a sort of lower heaven over one's head —— useful to keep off rain and snow, where the king and queen posts stand out to receive your homage, when you have done reverence to the prostrate Saturn of an older dynasty on stepping over the sill; a cavernous house, wherein you must reach up a torch upon a pole to see the roof; where some may live in the fireplace,some in the recess of a window, and some on settles, some at one end of the hall, some at another, and some aloft on rafters with the spiders, if they choose; a house which you have got into when you have opened the outside door, and the ceremony is over; where the weary traveller may wash, and eat, and converse, and sleep, without further journey; such a shelter as you would be glad to reach in a tempestuous night, containing all the essentials of a house, and nothing for house-keeping; where you can see all the treasures of the house at one view, and everything hangs upon its peg, that a man should use; at once kitchen, pantry, parlor, chamber, storehouse,and garret; where you can see so necessary a thing, as a barrel or a ladder, so convenient a thing as a cupboard, and hear the pot boil,and pay your respects to the fire that cooks your dinner, and the oven that bakes your bread, and the necessary furniture and utensils are the chief ornaments; where the washing is not put out, nor the fire, nor the mistress, and perhaps you are sometimes requested to move from off the trap-door, when the cook would descend into the cellar, and so learn whether the ground is solid or hollow beneath you without stamping.

我有时梦见了一座较大的容得很多人的房屋，矗立在神话中的黄金时代中，材料耐用持久，屋顶上也没有华而不实的装饰，可是它只包括一个房间，一个阔大、简朴、实用而具有原始风味的厅堂，没有天花板没有灰浆，只有光光的椽木和桁条，支撑着头顶上的较低的天，——却尽足以抵御雨雪了，在那里，在你进门向一个古代的俯卧的农神致敬之后，你看到衍架中柱和双柱架在接受你的致敬；一个空洞洞的房间，你必须把火炬装在一根长竿顶端方能看到屋顶，而在那里，有人可以住在炉边，有人可以往在窗口凹处，有人在高背长椅上，有人在大厅一端，有人在另一端，有人，如果他们中意，可以和蜘蛛一起住在椽木上：这屋子，你一打开大门就到了里边，不必再拘泥形迹；在那里，疲倦的旅客可以洗尘、吃喝、谈天、睡觉，不须继续旅行，正是在暴风雨之夜你愿意到达的一间房屋，一切应有尽有，又无管理家务之烦；在那里，你一眼可以望尽屋中一切财富，而凡是人所需要的都挂在木钉上；同时是厨房，伙食房，客厅，卧室，栈房和阁楼；在那里你可以看见木桶和梯子之类的有用的东西和碗橱之类的便利的设备，你听到壶里的水沸腾了，你能向煮你的饭菜的火焰和焙你的面包的炉子致敬，而必需的家具与用具是主要的装饰品；在那里，洗涤物不必晒在外面，炉火不熄，女主人也不会生气，也许有时要你移动一下，让厨子从地板门里走下地窖去，而你不用蹬脚就可以知道你的脚下是虚是实。
