Description

Technical Field

[0001] The invention belongs to the field of earthquake-resistant composite beams, and in particular relates to modular earthquake-resistant composite beams for public buildings and a use method thereof. Background Art

[0002] The interior of the earth is divided into three bottom layers: the crust, mantle and core. Houses and buildings are attached to the outermost crust. Earthquake damage is the damage caused by the strong vibration of the ground caused by seismic waves, which causes the collapse of houses and buildings on the ground and the resulting damage. Seismic waves are divided into three types according to their propagation mode: longitudinal waves, transverse waves and surface waves. Longitudinal waves are called P waves, which are propagation waves. They travel at a speed of about 6 kilometers per second in the crust and arrive at the epicenter first, causing the ground to vibrate up and down without being very destructive. Transverse waves, also called S waves, are shear waves. They travel at a speed of about 4 kilometers per second in the crust and arrive at the epicenter second, causing the ground to swing back and forth and left and right without being very destructive. Surface waves, also called L waves, are mixed waves generated when longitudinal waves and transverse waves meet on the ground. They travel at a speed of about 3 kilometers per second, have a large wavelength and amplitude, and are the main destructive factors causing houses and buildings.
