| Abstract: | Badong Ms5.1 earthquake in Hubei province caused various damages of simple buildings.The typical damage characteristics of adobe structures mainly includes partial collapse and vertical crack.While the damage patterns of masonry structures partial collapsing and falling.The analysis result of strong ground motion of the Earthquake show that ground motion concentrates in high frequency contents and its predominant period is of 0.1 s，which might lead to heavy damage of one storey simple structures.Poor stability of structure system of simple houses，insufficient intensity of components，and weak connection of nodes are the intrinsic factors of seismic damage. |
| Keywords: | Badong earthquake seismic damage investigation aseismic design ground motion acceleration natural period of vibration |
