本文对国内尚属首次采用框桁混合大跨度多层无粘结高效预应力混凝土工程进行了分析和评价,并结合设计宴例,就如何根据使用功能要求不同,分别选用的框架大梁和桁架结构的设计要点、计算方法、施工技术,以及所取得的良好效果等,均作了较完整的介绍,从而为多层和高层建筑提供了一种较好的结构形式和有益的经验。 This paper analyzes and evaluates for the first time a large-span, multi-span, non-bonding high-strength prestressed concrete project using frame-and-studded hybrids, and incorporates design feast cases. The framework girders and truss structures are selected according to their different functional requirements. The design points, calculation methods, construction techniques, and good results obtained were all presented in a more complete manner, thus providing a better structural form and useful experience for multi-storey and high-rise buildings.
