Overview

Service overview

Large-scale shaking table testing supports investigations of structural response, component interaction, dynamic damage and seismic protection measures under controlled earthquake excitation. The experimental platform accommodates large and heavy models, allowing studies that may be difficult to reproduce on conventional laboratory tables.

Research applications include building structures, nuclear facilities, hydraulic infrastructure, long-span structural systems and engineering equipment. Experimental programmes can examine acceleration, displacement, deformation and other response characteristics in conjunction with instrumentation and post-test analysis.

大型振动台试验通过可控地震动输入，研究工程结构的动力响应、构件相互作用、损伤演化及抗震减震措施。试验平台能够承载大尺寸、重载模型，为常规实验室振动台难以覆盖的研究对象提供试验条件。

应用方向包括建筑结构、核能相关设施、水工结构、大跨度结构及工程设备等，可结合传感测量和试后分析，研究加速度、位移、变形及其他动力响应指标。

Technical Details & Applications

Key Equipment

The large-scale seismic shaking table has a 20 m × 16 m working surface and a maximum payload of 1,350 t. Rated full-load maximum accelerations are 1.5g horizontally and 2.0g vertically.

Representative Experimental Cases

Full-scale elastic specimen testing of a multi-storey steel frame (geometric scale 1:1; total weight of 600 t).
Nuclear containment–soil–foundation interaction testing.
Vibration-control testing of a beam-string structural system.

Experimental Approach

A test programme may integrate representative ground-motion inputs, instrumented structural models and measured responses to examine seismic behaviour and structural performance.
