［摘要］印象·海南島仿生劇場(chǎng)是在原“?？谒澜?rdquo;原址上進(jìn)行改建和擴(kuò)建而成的，原結(jié)構(gòu)看臺(tái)蓬罩為懸挑13m的平板網(wǎng)架結(jié)構(gòu)，本次按照改建和擴(kuò)建的使用要求，需要懸挑25m。結(jié)合整個(gè)“海膽”的結(jié)構(gòu)形態(tài)，采用7點(diǎn)定位技術(shù)找形6條六次拋物線，形成前后拱，巧妙地將前后拱隱藏于“海膽”內(nèi)，使結(jié)構(gòu)從原來的懸挑結(jié)構(gòu)演化為桁架支撐拱殼結(jié)構(gòu)。結(jié)合概念設(shè)計(jì)和計(jì)算分析，對(duì)桁架支撐拱殼結(jié)構(gòu)體系進(jìn)行系統(tǒng)分析，并確定了最終結(jié)構(gòu)布置方案。闡述了為滿足結(jié)構(gòu)性能設(shè)計(jì)目標(biāo)所采取的分析方法和施工措施。

Abstract: Impression Hainan Island Bionic Theater is rebuilt and expanded from Haikou Water World. The original stand canopy is flat\|panel grid structure with 13m cantilever, and the new cantilever is 25m for the using requirement of renovation and expansion. Combined with the sea urchin structure, using 7 points positioning technology for form finding of 6 curves six times parabola, the front and back arches are hidden within the sea urchin, which makes the original cantilevered structure evolve to truss supported arch shell structure. Combining the conceptual design and calculation analysis, truss supported arch shell structure system was analyzed and chosen as the final layout of the structure. The analysis method and construction measures were expounded to meet the needs of structure performance.

Keywords: bionic theater; form finding; truss supported arch shell; six times parabolic
