抢救比萨斜塔     

丁大钧 《科学大众》1998,(12)

从奠基开始已有800多年的、举世闻名的意大利比萨斜塔是欧洲一颗灿烂的明珠。它不仅是比萨人民的骄傲,也是意大利人民的骄傲。比萨斜塔因传说中意大利比萨大学物理学家、天文学家伽利略,在塔上做了一次历史性的自由落体试验,形成“落体定律”而闻名于世。  相似文献   

DYNAMIC RESPONSE AND ENERGY DISSIPATION ANALYSIS OF THE WALL WITH HORIZONTAL SHORT KEYWAYS AND LOWRISE SHEARWALL     

戴航  丁大钧 《东南大学学报》1993,(1)

A new type of ductile lowrise shearwall with many short horizontalkeyways is proposed in this paper in order to improve the earthquake resistant behav-ior of ordinary lowrise shearwall.The behavior of this wall is studied through low-frequency cyclic loading test.Based on the test results,the paper puts forward thedifferent restoring force models for different lowrise shearwalls,and a program fortheir nonlinear dynamic analysis is worked out.Thr(?)h directly inputting earth-quake waves,the paper analyses the dynamic response and energy dissipation of 3types of lowrise shearwalls.The calculation results dem(?)strate that the newly de-vised ductile shearwall has good earthquake resistant behavior.  相似文献
