開合屋蓋結(jié)構(gòu)研究.pdf

1、天律大學(xué)博上學(xué)位論文摘要摘要開合屋蓋建筑是現(xiàn)代體育建筑的一個(gè)主要發(fā)展趨勢(shì)，越來越受到各界人士的青睞彥與常規(guī)體育建筑相比開合屋蓋建筑具有三大特性：復(fù)歸自然性、不利天氣影響的免疫性、綜合體育功能的可實(shí)現(xiàn)性。舊前世界上建成的小型開合屋、，蓋結(jié)構(gòu)已較多，但已建成的大型開合屋蓋體育建筑僅有十多座，在建的有七、八座。大型開合結(jié)構(gòu)的建成為當(dāng)?shù)貛砹撕芎玫慕?jīng)濟(jì)和社會(huì)效益，人們對(duì)建造大型開含屋蓋結(jié)構(gòu)的安全性、可行性的疑慮逐漸減小。然而，作為一種新型的建筑

2、結(jié)構(gòu)型式，在理論研究和工程實(shí)踐上還有許多課題需要解決，迄今研究性文章僅有幾十篇，且還主要局限在對(duì)具體工程的介紹上，只有日本等少數(shù)國家根據(jù)僅有的幾個(gè)工程制定了粗略的設(shè)計(jì)指針，開合屋蓋結(jié)構(gòu)設(shè)計(jì)還處在主要通過研究已建工程、從中尋求答案的水平上，缺少系統(tǒng)性的理論指導(dǎo)卉目前我國開合屋蓋建筑的實(shí)現(xiàn)還基本屬于空白。(研究性文章僅有幾篇。無疑，這種狀況不利于這種結(jié)構(gòu)的健康發(fā)展，開合屋蓋結(jié)構(gòu)的安全事故也表明，對(duì)這種結(jié)構(gòu)進(jìn)行深A(yù)、系統(tǒng)的研究是刻不容緩的課題

3、。在這種背景下開展了本文系統(tǒng)地研究工作移耋要研究?jī)?nèi)容有：1分析了開合屋蓋建筑的發(fā)展史，對(duì)現(xiàn)有典型開合屋蓋建筑進(jìn)行分析評(píng)述，對(duì)開合結(jié)構(gòu)的研究現(xiàn)狀進(jìn)行了總結(jié)，在分析其兩個(gè)主要發(fā)展階段的特點(diǎn)后，指出了開合屋蓋結(jié)構(gòu)進(jìn)一步發(fā)展的趨勢(shì)。2對(duì)開合結(jié)構(gòu)的開合方法進(jìn)行分類，提出了按屋蓋水平投影和立面形狀進(jìn)行開合單元?jiǎng)澐值脑瓌t和方法，對(duì)屋蓋開合方案的設(shè)計(jì)具有重要的指導(dǎo)意義。3對(duì)開合屋蓋的事故原因和影響開合屋蓋結(jié)構(gòu)安全的因素進(jìn)行分析，指出了解決開合屋蓋體系安

4、全問題的設(shè)計(jì)注意事項(xiàng)。在此基礎(chǔ)上，提出了開合屋蓋建筑的優(yōu)劣評(píng)價(jià)原則。4分析了各種開合結(jié)構(gòu)單元的受力特點(diǎn)和結(jié)構(gòu)方案；指出了各種類型的屋蓋單元結(jié)構(gòu)方案的布置原則及可能的結(jié)構(gòu)型式。提出了鈍化移動(dòng)屋蓋位移影響的6條措施。所得結(jié)論對(duì)屋蓋結(jié)構(gòu)方案的選型和設(shè)計(jì)具有很強(qiáng)的指導(dǎo)意義。5分析現(xiàn)有開合屋蓋結(jié)構(gòu)的屋面材料特點(diǎn)，指出膜材和金屬板是開合屋蓋的兩種主要屋面材料。根據(jù)已建丌合結(jié)構(gòu)屋蓋單元間防水構(gòu)造成敗實(shí)例，明確了開合屋蓋建筑的防水設(shè)計(jì)思想。天津大學(xué)博士
