摘要: 為研究江蘇園博園未來花園有機(jī)玻璃面板承載性能,設(shè)計(jì)了一個(gè)有機(jī)玻璃縮尺模型,并對該模型進(jìn)行了長期試驗(yàn)和短期試驗(yàn),以考察該縮尺模型在長期荷載和短期荷載作用下的受力性能及破壞模式. 結(jié)果表明,在長期荷載作用下,縮尺模型的蠕變現(xiàn)象并不明顯;在短期荷載作用下,該模型的極限承載力達(dá) 17kN,并表現(xiàn)為脆性破壞;模型破壞時(shí),試驗(yàn)測點(diǎn)處最大應(yīng)力約 6. 9MPa,測點(diǎn)最大位移為 104mm,說明該縮尺模型承載力較高,結(jié)構(gòu)安全可靠.

Abstract: In order to study the load-bearing capacity of the acrylic roof of Jiangsu Garden EXPO Park Future Garden, ascaled acrylic roof model was designed, and the long-term and short-term tests were conducted to investigate the mechanicalperformances and failure modes of the scaled model under long-term and short-term loads. The results show that the creepphenomenon of the scaled model was not obvious under long-term load. Under in the short-term load,the ultimate bearingcapacity of the model was 17kN, and the failure mode was brittle. When the model failed, the maximum stress at themeasuring point was approximately 6. 9MPa and the maximum displacement of the measuring point was 104mm which showthat the scaled model possesses a high load-bearing capacity, and the structure is safe and reliable.
