We do some research on the air gap response of the spar platform by numerical method.

利用数值计算方法对桁架式Spar平台气隙响应的影响因素进行了研究。

The results show that space finite analysis results are close to test ones, bottom chords suffer axial force and large in-plane bending, and the max stress is nearby each middle internode. The max stress of node crossbeams occurs in No.2 bottom flange, and that of internode crossbeams happens in ones lying in the middle of every internode. The concrete slab is in tension at the longitudinal direction, and also suffers bent at vertical loads. The degree of completely-composite model taking part in the combined actions is about 55%, while that of semi-composite model is 42%-43%. The combination of concrete slab and bottom chord increases the degree of floor system taking part in the combined actions, lightens the burden of bottom chord, and reduces out-of-plane bending of node crossbeams especially the ones near bridgehead. Stress and displacement of main truss can be evaluated by a equivalent plane rigid frame in preliminary design, and effective stiffness of bottom chords are composed of original ones and concrete slab, and the concentrated load from deck can be translated into uniform load.

研究结果表明：空间有限元分析结果与试验结果较吻合；下弦杆受到轴向拉力和较大的面内弯矩作用，各节间最大应力出现在节间中点附近；节点横梁最大应力发生在横梁2的下翼缘，节间横梁最大应力发生在位于端节间中部的小横梁上；混凝土板顺桥向整体受拉，并在竖向集中荷载作用下产生弯曲变形；全结合模型大部分节间内的桥面板参与主桁共同作用的程度为55%左右，半结合模型桥面板的参与程度为42%~43%；桥面板与下弦杆结合能够增加桥面板的参与程度，减轻下弦杆荷载，减少节点横梁尤其是靠近桥头横梁的面外弯曲；对桥梁进行初步设计时，主桁杆件的位移与内力可按照1个等效的平面刚架计算，下弦杆的等效刚度由原下弦杆截面和混凝土桥面板截面组合而成，桥面荷载可转化为均布荷载施加。

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。
