1·1 绪言 世界各国为了更好地了解贮料的流动状态及其对混凝土贮仓、筒仓和斗仓的影响都进行了大量的研究,结合极限强度设计的广泛应用,对贮仓、筒仓和斗仓的结构设计均要求有一个更为完善、安全、可靠的方法。 本《建议》代替发表在1968年7月份ACI学报上的ACI 313委员会65-37号报告《贮仓仓壁的设计与施工》。《建议》对筒仓,斗仓的结构设计、构造及施工规定均反映了最新的技术水平。 《建议》与ACI的其他标准一样,将定期修订和完善。《建议》是按最新的技术水平编制的,但是,今后如有更完善、更适用的方法时,将在修订版中予以补充。 静止状态下贮料的静压力按本《建议》介绍的方法计算,贮料处于流动状态时,设计压力要大于静压力。目前,建议用超压系数或冲击系数这种实用的方法来确定设计压力。
1.1 Introduction In order to better understand the flow state of stored materials and their effects on concrete silos, silos and silos, various countries in the world have conducted a lot of research, combined with the extensive application of ultimate strength design, for silos and cylinders. The structural design of the warehouse and silo requires a more complete, safe, and reliable method. This “Recommendation” supersedes the ACI 313 Committee Report No. 65-37 published in the July 1968 ACI Journal Paper “Design and Construction of Storehouse Walls”. The “Proposal” reflects the latest technology level in the structural design, construction and construction regulations of silos and silos. The “Proposal”, like other ACI standards, will be regularly revised and improved. The “Proposal” is compiled according to the latest technical level. However, if there is a more complete and applicable method in the future, it will be supplemented in the revised version. The static pressure of the storage material in the static state is calculated according to the method described in this Recommendation. When the storage material is in the flowing state, the design pressure is greater than the static pressure. At present, it is recommended to use the practical method of overpressure coefficient or impact coefficient to determine the design pressure.
