超限结构振动台模型制作及试验方案设计
首发时间:2008-09-22
摘要:武汉世茂锦绣长江A2地块1号楼1-3单元,层数56层,建筑面积65698m2。平面呈“T”型,建筑高度179.6m,超过现行《高层建筑混凝土结构技术规程》B级高度规定,属超限高层建筑工程。为研究它在地震作用下的抗震性能,对其进行缩尺(1/30)模型的振动台试验研究。本文主要介绍该振动台试验模型材料的选取,动力相似关系的确定以及试验方案的设计,并针对超高层结构模型尺寸小,施工困难的特点,提出适当简化的方法。

Shaking Table Model Making and the Test Program Design for the Ultra Limits Structure
Abstract:Wuhan ShiMao JingXiu ChangJiang A2 Block Building 1 unit 1-3 has 56-storeys and an area of 65698 m2. Plane with \\\\\\\\\\\\\\\"T\\\\\\\\\\\\\\\" type, building height is 179.6 m. More than the current 《high-rise building concrete structures technical point of order》 B-class high, belongs high-rise building . To study its role in the earthquake of seismic performance, its reduced scale (1/30) model on the shaking table test. This paper mainly describes the shaking table test model of material selection, the dynamic similitude-scaling relationship and design of the test program; and for high-rise structure model’s small size, the characteristics of the construction difficulties, to make appropriate simplified approach.
Keywords: ultra limits structure similar theory shaking table model
