摘要: 延安大學(xué)新校區(qū)圖書館整體建筑平面約呈 8 字形,建筑立面采用了寶塔及窯洞層層收進(jìn)的表現(xiàn)形式,但收進(jìn)的尺度又遠(yuǎn)小于柱距.如何保證建筑立面及室內(nèi)空間整體效果的同時(shí),又能夠做到結(jié)構(gòu)方案最優(yōu)是難點(diǎn).圍繞此新的退臺形式,著重分析了梁上柱、懸挑梁、斜柱等三種方案各自的優(yōu)缺點(diǎn).三種方案均不太理想,通過與建筑協(xié)商,局部調(diào)整了建筑軸網(wǎng)尺寸.最終確定在建筑南側(cè)及中部細(xì)腰四個(gè)角部設(shè)置斜柱,在東、西側(cè) 5 層懸挑大于4m 處設(shè)置梁上柱,東、西側(cè) 6 層懸挑小于 3m 時(shí)按懸挑梁設(shè)計(jì),實(shí)現(xiàn)了建筑東、南、西、北不同立面效果,滿足了室內(nèi)使用空間的要求.對結(jié)構(gòu)進(jìn)行了詳細(xì)的計(jì)算分析.結(jié)果表明,斜柱對與之相連的樓板及梁有一定的拉力作用,在設(shè)計(jì)過程中應(yīng)采取相應(yīng)的加強(qiáng)措施保證結(jié)構(gòu)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.
