Background
Earthquake (also called earthquake and earth vibration) is a natural phenomenon that the earth crust vibrates during the process of quickly releasing energy and earthquake waves are generated during the process. Statistically, about more than 500 ten thousand earthquakes occur on earth every year, i.e., more than ten thousand earthquakes occur each day. Most of them are too small or too far away to be felt by people; the earthquake which can really cause serious harm to human beings is about more than ten and twenty times; there are about two earthquakes that can cause particularly serious disasters.
In order to resist the sudden attack of an earthquake, attention is often paid to the repair and maintenance of old houses. If the wall body has cracks or is in a wrong flashing state, the wall body needs to be repaired in time; periodically plastering the easily weathered and shortbread soil wall; the roof leakage can be repaired quickly; and accumulated water around the house is immediately discharged after heavy rain so as to avoid soaking the wall base for a long time. Wooden beams, columns and the like are required to prevent decay and worm damage, and if damaged, the wooden beams, the columns and the like are overhauled in time.
In the prefabricated building which is currently emerging, the requirements for earthquake resistance are the highest. Due to the adoption of the splicing mode, the joint is easy to break in earthquake, so that the earthquake-resistant design of the connecting joint of the fabricated building is very necessary.
