摘要:

针对混凝土模块化建筑中传统叠合楼板现浇层施工效率低、现场湿作业量大等问题,提出一种由预埋钢筋、现场搭接钢筋及现浇超高性能混凝土(UHPC)构成的分布式水平连接节点替代整体现浇层的分离式楼板体系。以某28层宿舍楼为例开展模块化设计,建立了考虑节点轴向、面内剪切及面外剪切刚度的整体有限元模型,分析结构在风荷载与地震荷载组合下的响应,并系统开展节点不同方向刚度的参数化分析。结果表明:分离式楼板体系在水平荷载组合作用下的楼层位移和层间位移角最大值均不超过规范限值; 楼层剪力最大值出现在结构底层,最大值为9 300 kN; 分布式水平连接节点在水平荷载下以轴向和面内剪切方向受力为主; 当节点轴向刚度大于1×10⁵ kN·m^-1、面内剪切刚度大于3×10⁴ kN·m^-1时,可保证结构的楼层位移及层间位移角满足规范要求; 所提出的分布式水平连接节点分离式楼板体系可以显著提高施工效率,同时保证结构的安全性,适用于混凝土模块化高层建筑,可为同类工程提供设计参考与理论依据。

Abstract:

Aiming at the problems of low construction efficiency and large amount of on-site wet work in the cast-in-place layer of traditional composite floor in concrete modular buildings, a separate floor system composed of embedded steel bars, on-site lap steel bars and cast-in-place ultra-high performance concrete( UHPC )was proposed to replace the conventional cast-in-place layer. Taking a 28-story dormitory building as an example, the modular design was carried out. The overall finite element model considering the axial, in-plane shear and out-of-plane shear stiffness of the joints was established. The structural response of the structure under the combination of wind load and seismic load was analyzed, and the parametric analysis of the stiffness of the joints in different directions was systematically carried out. The results show that the maximum values of story drift and story drift ratio of discrete diaphragm system under the combination of horizontal loads do not exceed the code limits. The maximum value of the floor shear force occurs in the bottom floor of the structure, and the maximum value is 9 300 kN. Under horizontal loads, the distributed joints are primarily subjected to axial forces and in-plane shear forces. Structural story drift and story drift ratio could meet the requirements of the codes when the axial stiffness of the joint exceeds 1×10⁵ kN·m^-1 and the in-plane shear stiffness exceeds 3×10⁴ kN·m^-1. The proposed discrete diaphragm system employing distributed horizontal connection joints can significantly enhance construction efficiency while ensuring structural safety, making it suitable for high-rise concrete modular buildings and providing valuable design references and a theoretical basis for similar projects.
