The magnitude and intensity relation that is coincided with Yunnan Area by the statistical analysis is shown as Ms = 1.7-+ 0.6I. or Ms= 4.7-0.3I. + 0.06I.
The article relates the principles of seismic intensity regionalization, the limits of intensity distribution,abnormal intensity, gives the macroseismic parameters (h=11.2km, earthquake scale:5.8ML) and points out that the intensity rating by the macroexaminations was in keeping with that of the acceleration of the strong aftershocks by the strong motion seismograph by and large.
In case the earthquake intensity of a city with a 10% exceeding probability lies between 6.5°~6.8°,7.5°~7.8° or 8.5°~8.8°,the optimal fortification intensity and earthquake parameters of such a city can be determined by the engineering policy-making analysis of the results of seismic hazard and condition of the city combining with the aseismic fortification delimitation of the city.
The analysis shows that the horizontal acceleration amplification of 3.0, 2.5, 2.0 along the stream is appropriate for the design earthquake intensity of 7, 8 and 9 respectively.
Let {N(t), t≥0} be the nonhomogenous Poisson process with cumulative intensity parameter Ν (t), {δt,t ? 0} the age process, and {γt,t ? 0} the residual lifetime process.
Generally, The risk-neutral default intensity λQ is not equal to the empirical or actual default intensity λ.
It can be concluded that the newly built feeding-sample system can increase the spectral line intensity by about two to three times and decrease the detection limit by about 2 to 10 times.
The results indicated that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes.
Each NMR spectra was data-processed to provide 238 intensity-related descriptors as input coordinates in a multidimensional space and analyzed by PR method.
By observing the drilling cores of He 152, Wang 59, Niu 38, Niu 22 and so on, we found that the vertical sequences of the seismite are different because of the differences in structure and seismic intensity.
The model is applied to the seismic response analysis of an arch dam with a height of 292m designed to a seismic intensity of IX.
From the test results, it is demonstrated that the CFT arch structures are capable of resisting severe ground motions and that CFT arches offer a credible alternative to reinforced concrete arches, especially in regions of high seismic intensity.
Conversion between seismic intensity and peak ground shaking
Finally, a methodology of converting seismic intensity from response spectrum of design earthquake is also discussed, and the conversion scheme is recommended.
The distribution of affected intensity shows, about 53% of cities have even not been affected by earthquake intensity VI, and 44% of cities have been hit by earthquake intensity VII to IX.
By comparing with the standard earthquake intensity attenuation relationship, the abnormal damage distribution of the earthquake is found, so the relationship of the abnormal distribution with tectonics, site condition and basin are analyzed.
Inelastic coupled response of eccentric buildings with respect to different earthquake intensity
Using five-story shear models, the inelastic torsional coupled response of eccentric buildings to different earthquake intensity was studied.
Generally, the building designed by spectral modal analysis method has a tendency to move translationally as the earthquake intensity increases.
