In earthquake-resistant structure technical field.
Background technique
China's specification is provided fortification against earthquakes, and there are three level targets, i.e. " small earthquakes are not bad, medium ones can be repaired, and large ones cannot fall ".
" small shake " is equivalent to " frequently occurred earthquake ", and the earthquake intensity for being 63% for outcross probability in statistical analysis 50 years, is the
One level earthquake intensity；" middle shake " is equivalent to " earthquake of setting up defences ", to statistically analyze the earthquake intensity that outcross probability is 10% in 50 years, is
The second level earthquake intensity；" big shake " is equivalent to " rarely occurred earthquake ", strong to statistically analyze the earthquake that outcross probability is 2~3% in 50 years
Degree is the earthquake intensity of third level.
Recent decades, China experienced the earthquake of multiple large size, and to guarantee national life security, China is standardized to " middle shake
Can repair " and the realization of " no collapsing with strong earthquake " two targets done sufficient research and regulation.For the antidetonation of " no damage in small earthquake "
It sets up defences target, predominantly stays in the checking of bearing capacity of frequently occurred earthquake effect flowering structure.There is no pay attention to meet more for China's specification at present
Building structure applicability analysis under earthquake.The only design of structure serviceability limit state at present in the world, without real
The antidetonation applicability of meaning designs, more without antidetonation applicability analysis method.However, under frequently occurred earthquake effect, structural elements,
