列宁格勒城市设计院设计了一种防震系统,采用此种防震系统的住宅已有效地经受住了几次强震的考验,那几次地震的强度都超过了不久前袭击过墨西哥城的地震。按照该设计院的设计,在位于地壳断裂带上的东西伯利亚城市北贝加尔斯克建成了第一批高层住宅,这批住宅是按抗 X 度(烈度)以下地震设计的。设计院总结构师约费诺夫作了说明:在住宅的基础和地面以上的结构之间,采用了称之为防震联结的措施。当地震发生时,结构可以自由地相对移动,从而缓冲土地震动的影响。这样,牢固的金属构件便可抵消地震的大部分能量。此类防震系统的有效性 The Leningrad Urban Design Institute has devised an earthquake-proof system, and houses using such earthquake-resistant systems have effectively stood the test of several strong earthquakes that have outweighed the recent earthquake that hit Mexico City . According to the design of the design institute, the first high-rise houses were built in the northern Siberian city of Begursk on the crustal fault zone. The houses were designed for earthquakes up to X degree (intensity). Jovanov, chief architect of the Institute of Design, made a remark: Between the foundation of a house and the above-ground structure, a measure called the anti-vibration joint was adopted. When an earthquake occurs, the structure can move freely relative to each other to cushion the impact of the earthquake. In this way, strong metal components can offset much of the seismic energy.
