［摘要］安徽蚌埠医学院第二附属医院新建院区使用功能包括病房楼、门诊医技楼等，结合医院结构设计，通过分析计算大型医院结构设计中常见的问题，总结了解决该类问题的方法和思路，为解决该类实际工程提供参考。基于平面复杂的大型医院建筑的结构优化方案设计，通过几种结构布置方式的计算、比较及分析，详细研究了顶层报告厅抽柱形成的大跨所采用的最优布置方式，方案采用空腹楼盖+钢筋混凝土暗梁的结构布置方式，既能满足建筑对于净高的要求，又能保证其在正常使用及承载情况下的安全性要求。对于静定长悬臂梁的结构安全设计，采用拉杆的处理方式，并相应采取一系列构造加强措施，能够确保其具有足够的承载力。此外，对于如何解决病房楼超长、门诊医技楼平面不规则等问题也进行了分析，可供设计人员参考。

Abstract: The New Second Affiliated Hospital of Bengbu Medical College buildings compose of the ward, outpatient medical technology building, etc.. In combination with the hospital structural design, by analyzing and calculating common problems of large hospitals, methods and ideas were summed up to solve the kind of problem and provided reference to solve practical engineering. Based on the structural design of large and complicated structures, the common problems and the solutions in the design of large-scale structure of hospital were analyzed. By detail calculation and analysis of different structure projects, the optimal structure for the large span of the top floor lecture hall was designed. In the optimal project, the hollow floor combined with the reinforced concrete concealed-beams structure was selected to satisfy the requirement of high clear height and safety performance. As for safety design of the statically determinate long cantilever beam, davit and corresponding strengthening measures were taken to make sure the high bearing capacity. Besides, other design problems were also analyzed, including super-long of ward, irregular plane of outpatient and medical technology building, etc., which can offer reference for similar structure design.

Keywords: architecture selection; single-span frame; vertical earthquake; super-long structure; hollow floor
