摘要
建滔总部大厦为结构高度220m的混合结构,混凝土核心筒完全偏置于塔楼的东侧,以形成开阔的办公空间。为实现室内大空间与立面通透性的建筑效果,办公区采用中间无柱、在东西两侧以小吊柱吊挂组合楼盖的竖向传力体系。小吊柱悬挂于设置在避难层的巨型桁架,只有角部4根矩形钢管混凝土巨柱与南北两侧的巨型斜撑落地,形成巨型支撑框架-偏置核心筒体系。塔楼虽然没有严重不规则的超限内容,但是由于其特殊的建筑造型与结构体系,属于国家规范没有列入的特殊类型的超限高层建筑。设计团队结合本项目的建筑和结构特点,进行了充分的结构概念设计,结合大量的计算分析与深入的技术论证,检验了结构体系的合理性,确保结构具有可靠的竖向传力路径与抗风和抗震性能。
The Kingboard Headquarters Building is a mixed structure with a structural height of 220 meters. The concrete corewall is arranged at the east side of the building to form a larger open office space. In order to achieve the architect’s pursuit of the large indoor space and the permeability of the facade, the office area adopts the vertical force transmission system without middle columns and with composite floor in east and west sides hung by little hanging columns. Little hanging columns are suspended on giant trusses setting on the refuge floor, and only four rectangular concrete-filled steel tube mega columns at the corners and mega braces on the north and south sides land, forming a mega braced frame and eccentrically-arranged corewall system. Although the tower has no serious irregular out-of-code contents, it is a special type of super high-rise building that is not included in the national code due to its special architectural shape and structural system. Combined with the architectural and structural characteristics of the project, the design team carried out a full structural conceptual design. Combined with a lot of calculation and analysis and in-depth technical demonstration to test the rationality of the structural system and ensure that the structure has a reliable vertical force transmission path and wind resistance and seismic performance.
