摘要：为研究江苏园博园未来花园有机玻璃面板承载性能，设计了一个有机玻璃缩尺模型，并对该模型进行了长期试验和短期试验，以考察该缩尺模型在长期荷载和短期荷载作用下的受力性能及破坏模式。结果表明，在长期荷载作用下，缩尺模型的蠕变现象并不明显；在短期荷载作用下，该模型的极限承载力达17kN,并表现为脆性破坏；模型破坏时，试验测点处最大应力约6.9MPa,测点最大位移为104mm,说明该缩尺模型承载力较高，结构安全可靠。

Experimental study on load-bearing capacity of scaled acrylic roof model of Future Garden
Abstract: In order to study the load-bearing capacity of the acrylic roof of Jiangsu Garden EXPO Park Future Garden, a scaled acrylic roof model was designed, and the long-term and short-term tests were conducted to investigate the mechanical performances and failure modes of the scaled model under long-term and short-term loads. The results show that the creep phenomenon of the scaled model was not obvious under long-term load. Under in the short-term load, the ultimate bearing capacity of the model was 17kN, and the failure mode was brittle. When the model failed, the maximum stress at the measuring point was approximately 6.9MPa and the maximum displacement of the measuring point was 104mm which show that the scaled model possesses a high load-bearing capacity, and the structure is safe and reliable.
