模拟地震振动台是研究工程结构物的破坏机理、验证抗震理论、考核抗震措施的不可缺少的现代科学实验手段。根据国家下达的研究任务,由中国建筑科学研究院抗震所负责总成并组织研制3×3 m 模拟地震振动台。该振动台第一期工程是以实现单向水平正弦运动为基本目标,最终将建成一座中型的三向振动台(图1)。该振动台于1983年8月11日～14日在北京通过部级鉴定,各项技术指标均已达到第一期工程的设计要求,是我国自己研制成功并已投入使用的第一台模拟地震振动台。 Simulating seismic shaking table is an indispensable modern scientific experimental method to study the failure mechanism of engineering structures, verify the theory of anti-seismic, and evaluate anti-seismic measures. According to the research mission issued by the state, the seismic assembly of the China Academy of Building Research and the organization of the 3 × 3 m simulated seismic shaking table are organized. The first phase of the shaker is based on the realization of one-way horizontal sinusoidal motion as the basic goal, and ultimately will be built into a medium three-way shaker (Figure 1). The vibration table in August 11, 1983 to 14 at the ministerial level in Beijing through the identification, the technical indicators have reached the first phase of the design requirements, is our own successful development and has been put into use the first simulation earthquake Shaker.
