( Tsinghua-Yuan Architectural Design Ltd., Shenzhen 518052, China)Abstract: The shock-bearing stairs mentioned here is fabricated lightweight steel construction, and some joints designed specially linking structural members can offer shock-bearing properties to the stairs structure. To reduce the harmful influence of dynanuc properties on the whole structure by rigidity of stairs into full play, the unnecessary confinement of degrees of freedom was relaxed in the three dimensions for every members. Simultaneously stable load-bearing capacity was retained, and the working conditions of stairs itself were improved entirely during earhquake. The comprehensive benefit of this reformation is remarkable.
Keywords: shock-bearing design; degree of freedom; relax unnecessary confmement
