大连国际会议中心的筒体采用“钢管角柱-钢桁架暗支撑架混凝土组合核心筒”。该结构各核心筒均根据建筑的需求开设了洞口,且整个结构质量、刚度分布不均,筒体受力较为复杂。在核心筒的抗震设计中,如何保证筒体角部钢管柱柱脚与混凝土基础具有良好的共同工作性能,保证结合部位的锚固性能,是其关键技术之一。对这部分钢管柱进行抗拔试验研究,以确保在地震作用下整个筒体以及结构的安全。试验表明,混凝土基础中配置竖向抗拔钢筋和水平分布钢筋均能有效提高抗拔柱的锚固承载力。
Dalian International Convention Center of the cylinder using “steel angle column - steel truss dark frame concrete combination core tube ”. The structure of the core tube are opened according to the needs of the construction of the hole, and the entire structure of the quality, uneven distribution of stiffness, the cylinder stress is more complicated. In the seismic design of the core tube, how to ensure that the column corner of the cylinder body and the concrete foundation have good common working performance and ensure the anchorage performance of the joint is one of the key technologies. This part of the steel column pullout test study to ensure that the earthquake under the effect of the entire cylinder and the structure. The test shows that the vertical reinforcement and the horizontal distribution reinforcement can effectively improve the anchorage capacity of the anti-pull column in the concrete foundation.
