摘要:

本研究基于宿迁地区极端气候引发的日光温室倒塌问题,旨在提高苏式日光温室的结构安全性和稳定性。研究结合国家标准GB/T 51183—2016《农业温室结构荷载规范》和GB/T 51424—2022《农业温室结构设计标准》,针对16 m跨度的苏式日光温室开展荷载计算与结构优化研究。通过Midas Gen软件构建三维有限元模型,计算宿迁10 a重现期的风雪荷载,整合408种荷载组合进行包络分析。结果显示,最不利荷载组合为不均匀雪荷载主导的工况,拱架前柱脚处应力峰值达538.7 N/mm2。针对薄弱点提出优化方案,即在主拱架前柱脚增设竖向立柱,优化后应力峰值降至191.2 N/mm2,竖向变形量减少至40.2 mm,优化后的变形量较未优化前降低了73%。研究表明,通过局部结构加固可显著改善温室的应力集中与失稳风险,为苏式日光温室在宿迁及类似气候条件地区的推广应用提供了结构安全保障,并为同类设施的结构优化提供参考。

Abstract:

To address the collapse problem of Jiangsu-style solar greenhouses caused by extreme climate in Suqian area, this article combines the national standards "Code for Load of Agricultural Greenhouse Structures" (GB/T 51183-2016) and "Design Standards for Agricultural Greenhouse Structures" (GB/T 51424-2022) to conduct load calculation and structural optimization research on a 16 meter span solar greenhouse. A three-dimensional finite element model was constructed using Midas Gen software to calculate the wind and snow loads during the 10-year return period in Suqian. 408 load combinations were integrated for envelope analysis. The results showed that the most unfavorable load combination was dominated by uneven snow loads, with a peak stress of 538.7 N/mm2 at the front column base of the arch. An optimization plan for the weak points was proposed, which is to add vertical columns at the front column base of the main arch. After optimization, the peak stress was reduced to 191.2 N/mm2, the optimized vertical deformation amount was reduced to 40.2 mm, representing a 73% reduction compared to the pre-optimized state. Research has shown that local structural reinforcement can significantly improve the stress concentration and instability risk of Jiangsu-style greenhouses, providing reference for structural optimization of similar facilities.
