Based on principle of bionics, this paper introduces a design of root-bionic seismic foundation so as to enhance the seismic capability of structures in high seismic intensity area.
Combined with the survey data of historical earthquake in Xinjiang, the seismic intensity attenuation law has been fitted with multiple regression method.
Building seismic damage is the main basis to evaluate seismic intensity.
And then the seismic intensity attenuation relations along major axis, minor axis and mean axis are established separately.
The seismic intensity regionalization map of Sichuan and neighboring area was given according above standard and methods map of China Both are about the same.
The seismic influence field reflects the space distribution of seismic intensity or space-related seismic ground motion field.
A method is presented for use in establishing probability model of seismic intensity attenuation in regions with abundant data of isoseismal maps.
The seismic intensity in epicenter area reaches Ⅶ degree and the earthquake caused different level damages among 13 villages or towns of Xinlong,Beiyu and Litang counties and the area with heavy hazard is 200 square kilometers and light hazard area is 700 square kilometer.
The factors relating to shear wall discussed in this paper are seismic intensity, site soil condition, weight and height of building, and top displacement of structure etc.
According to the seismic intensity data of Chongqing and nearby regions, we present the seismic intensity attenuation law for the regions of Chongqing and vicinity by using the regression method.
See process for basic parameters such as ambient temperature seismic intensity and wind pressure value.
The formula of seismic intensity attenuation fitted by using 37 isoseismal lines of 14 earthquakes in Shandong and near area.
Lower coefficient of earthquake seismic intensity of the security role in the decision to lower the overall structure of the yield of standard size and structure of the extensive demand.
China's seismic intensity on the table, the people the impression that the general level of damage to housing and other phenomena described, can be used as the basis for determining intensity.
