光伏支架结构采用中美欧规范设计差异分析

Analysis of the differences in the structural design of PV supports in Chinese code, American code and European code

随着国家"一带一路"战略不断推进,中国企业在国外承揽的光伏工程不断增多,其中绝大部分项目业主要求设计单位采用美欧等国际通用规范进行投资报价或结构设计。利用有限元软件SAP2000,基于某典型光伏支架结构设计经验,分别采用中国规范、美国规范及欧洲规范对该光伏支架进行结构计算分析,研究并总结了不同规范在设计方法、风荷载取值、有限元内力计算值、截面选取及上部支架钢材工程量等重点内容的异同。最后,提出针对此类项目的设计建议及结论,以期为海外光伏工程建设和相关设计人员提供借鉴。

With the continuous promotion of the national"One Belt And One Road"strategy,the number of photovoltaic projects undertaken by Chinese enterprises abroad keeps increasing,and most of the project owners require the design units to adopt international general specifications such as American and European standards for investment quotation or structural design.Based on the structural design experience of a typical photovoltaic support,using the finite element software SAP2000,adopt the Chinese code,American code and European code,the structural calculation and analysis of the photovoltaic support are carried out,and the similarities and differences in the design method,wind load value,finite element internal force calculation value,section selection and steel quantities of the upper support in different codes are studied and summarized.Finally,the design suggestions and conclusions for such projects are put forward,in order to provide reference for overseas photovoltaic engineering construction and relevant designers.
