摘要: 延安大学新校区图书馆整体建筑平面约呈 8 字形,建筑立面采用了宝塔及窑洞层层收进的表现形式,但收进的尺度又远小于柱距.如何保证建筑立面及室内空间整体效果的同时,又能够做到结构方案最优是难点.围绕此新的退台形式,着重分析了梁上柱、悬挑梁、斜柱等三种方案各自的优缺点.三种方案均不太理想,通过与建筑协商,局部调整了建筑轴网尺寸.最终确定在建筑南侧及中部细腰四个角部设置斜柱,在东、西侧 5 层悬挑大于4m 处设置梁上柱,东、西侧 6 层悬挑小于 3m 时按悬挑梁设计,实现了建筑东、南、西、北不同立面效果,满足了室内使用空间的要求.对结构进行了详细的计算分析.结果表明,斜柱对与之相连的楼板及梁有一定的拉力作用,在设计过程中应采取相应的加强措施保证结构的安全性.

Abstract:The overall building plan of the library in the new campus of Yan’ an University is about 8-shaped,and thebuilding facade adopts the form of pagoda and cave retraction layer by layer,but the retraction scale is far smaller than thecolumn distance. How to not only ensure the overall effect of the building facade and indoor space,but also achieve theoptimal structural scheme is the difficulty. Focusing on this new form of setback,the advantages and disadvantages of thethree schemes of beam column,cantilever beam and inclined column were analyzed emphatically. All three schemes are notideal,and through consultation with the architect,the size of the building grid has been partially adjusted. It is finallydetermined to set up inclined columns at the four corners of the middle narrow waist and the south side of the building,setup beam upper columns where the cantilever is greater than 4m on the 5th floor on the east and west sides,and design thecantilever beams when the overhang on the 6th floor on the east and west sides is less than 3m,which realizes the differentfacade effects of the east,south,west and north of the building,and meets the requirements of indoor use space. Thestructure was calculated and analyzed in detail. The results show that the inclined column has a certain tensile force on thefloor and beam connected to it,and corresponding strengthening measures should be taken in the design process to ensurethe safety of the structure.
