武汉雷神山医院结构设计

武汉雷神山医院为收治确诊感染新型冠状病毒肺炎患者的应急临时医院,由隔离医疗区和医护生活区组成。工程采用了三种不同的装配式钢结构体系以适应建筑功能特点,满足快速施工的要求。具体而言,病区护理单元采用轻型钢结构模块化组合房屋(箱式房),ICU及医技单元采用钢框架体系,医护生活区采用轻钢活动板房。针对不同体系的特点,完成了结构布置与构造设计,并进行了相关计算分析,结果表明,结构受力及变形满足规范要求。根据场地土质情况和上部结构荷载,对地基承载力进行了复核。结合现有硬化地坪条件,因地制宜地采用了H型钢支墩、条形支墩和平板式筏形基础等多种基础形式,满足了建筑构造和结构安全的要求。最后,介绍了为配合特殊条件下的施工所采取的合理的设计方法和应对措施。通过本工程的实践,验证了结构选型的合理性与设计的可靠性。

Structural design of the Leishenshan Hospital in Wuhan

Wuhan Leishenshan Hospital, which is composed of isolation medical area and medical living area, is a temporary emergency hospital for patients with confirmed COVID-19 infection. Three different prefabricated steel structural systems were adopted in the project to adapt to the building functional characteristics and meet the requirements of rapid construction. Specifically, the nursing unit in the ward adopts the light steel structure modular composite house(box-shaped house), the ICU and medical technology unit adopt the steel frame system, and the medical living area adopts the light steel prefabricated house. According to the characteristics of different structural systems, the structural layout and structural design were completed, and the relevant calculation and analysis were carried out. The analysis results show that the structural mechanism and deformation meet the requirements of the code. According to the soil condition of the site and the load of the superstructure, the bearing capacity of the foundation was rechecked. Combined with the existing hardened floor conditions, various foundation forms were adopted such as H-shaped steel buttress, strip buttress and flat raft foundation, to meet the requirements of building structure and structural safety. Finally, the reasonable design methods and corresponding measures for the construction under special conditions were introduced. Through the practice of this project, the rationality of structural system selection and the reliability of the design were verified.
