摘要:江苏园博园未来花园有机玻璃水幕是目前我国建筑领域最大的结构有机玻璃项目,对其进行原位加载试验具有重要的意义。对未来花园有机玻璃水幕中的5号伞进行了1.5倍设计荷载下(150mm深水)的原位加载试验,并持载15d。通过试验获得了有机玻璃结构的位移和应变的发展规律及其与温度的关系。研究表明:在1.5倍设计荷载下,有机玻璃水幕的变形和应变均满足设计要求,在持载15d内未发生明显的蠕变现象,同时有机玻璃水幕板底的应变远高于肋底,并与温度存在相关关系。

Abstract: The acrylic water curtain in of Jiangsu Garden EXPO Park Future Garden is the largest structural acrylic buildings in China at present, and it is of great significance to carry out in-situ loading tests on it. The No. 5 umbrella in the acrylic water curtain of the Future Garden was tested in-situ under 1.5 times of the design load(water depth of 150mm) which was then held for 15 days. The development of displacement and strain of acrylic structure and relationships with temperature were obtained. Test results indicate that under 1.5 times of the design load, the deformation and strain of the acrylic water curtain meet the design requirements, and no obvious creep occurred within 15 days of holding load. Meanwhile, the strain at the bottom of plate is much higher than that at the bottom of rib, and strain and temperature are highly correlated.
Keywords: Jiangsu Garden EXPO Park Future Garden; acrylic; in-situ loading; temperature; deformation; strain
