地震

From local records of earthquakes and aftershocks, we knew that on the day following a magnitude7.3 event , the chance of another large shock striking within100 kilometers is nearly67 percent—20,000 times the likelihood on any other day.

从当地的地震和馀震记录来看，在100公里範围内，我们知道在规模7.3的地震后，发生其他大地震的机率为67%是平常的两万倍。

The crustal movement change in 1997~2001 in coastal areas of Fujian have relative to growth and occurrence of CHI-CHI and East of Hualian earthquakes in time not only, but their growth mechanism are consistency which have decided by stress field of growing these two time earthquakes.

福建沿海地区在1997～2001年期间出现的地壳运动的变化不仅在时间上与集集、花莲东两次7级大地震的孕育发生相关，而且二者在形成机理上一致，都是由孕育这两次地震的应力场决定的。

Analyzing the MS4.8 earthquake on May 17, 1999 in Wanning coastwise, it is suggested that this event characterized by isolated type, and the seismogenic fault is the subsidiary fracture in the NE strike between the Xinglong-Longgun fault and the Qiongdongnanhai fault, which make a feature of strike-slip.

对1999年5月17日万宁近海MS4.8级地震进行了总结。分析认为，这次地震属孤立型，发震断层为NE向的兴隆-龙滚断裂和琼东南海断裂之间的次一级断裂，具有走滑特征。

Some colleger uses university of on potato net one paragraph of Sichuan the video that the mobile phone films, be as long as 1 minute of 50 seconds, recorded an earthquake the dormitory is mixed at that time the circumstance inside campus, the rate that exceeds 100 times with every second by refresh.

This title will do the architecture design for the office building and give some illumination , will tell of the disposal of structure and draw the reasonable columniation plan according to the architecture design and the correlative codes.

本文将对办公楼进行建筑设计，并对设计给予相应的说明，详诉本办公楼的结构布置，根据建筑设计和相关规范条款给出合理的柱网图；在综合考虑了结构在各种恒载、活载、风荷载以及地震荷载作用下的情形后，详细的分析了结构在风荷载和地震荷载作用下的横向和纵向的各种性能，具体的计算了结构的梁、柱的弯矩、轴力、剪力，并进行了相应的内力组合，并由此进行了框架配筋部分，最后完成了柱下独立基础的有关计算。

Thirdly, a new type base isolation system, i. e., slide-limited friction base isolation system is presented in this paper. Based on this system, harmonic and subharmonic periodic response of S-LF subjected to harmonic motion is investigated by using Floquet theory. Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.
