【摘要】 本文通过多项工程实例讨论了一种新型钢筋混凝土空腹式楼 (屋 )盖结构体系——钢筋混凝土空腹夹层板柱结构体系在大跨度 (18～ 24m)单层与多层建筑结构中应用时的“经济合理跨度”，并与钢筋混凝土密肋井字楼 (屋 )盖进行对比分析，说明其良好的技术经济指标和建筑功能。并讨论了预应力混凝土空腹夹层板柱结构体系在大跨度 (18～ 36m)建筑结构中应用时的“经济合理跨度”及其结构性能，以利推广应用。更多还原

【Abstract】 According to the design of several actual buildings, this paper discusses the economical and rational span length of reinforced concrete vierendeel sandwich plates used in long span (18～ 24m) single-story and multistory buildings, and reveals their good economical index and architectural function in comparison with the waffle slabs. The economical span length and structural behavior of the prestressed concrete vierendeel sandwich plates are discussed as well.更多还原
