Form Art and Function Analysis of Outdoor Stairs

Stairs are an important structural component in the architectural space design.It not only serves as a link between landscapes,but also a highlight of the space.Interpretation of stairs can be carried out from the form and function of stairs.This paper mainly takes the outdoor stairs as the research object,which is a building component to solve the vertical traffic function of the building,and selects some stairs designs worldwide for the analysis.Focusing on architectural design,the study investigates the expression form of each component of the outdoor stairs,and explores the diversified designs of the stairs.The paper urges designers to pay close attention to the problems of stair design in essence,to deeply understand the forms and methods of stair expression,to expand the breadth of architectural design thinking,to pursue in-depth understanding of the inherent laws of building generation,and to improve the quality of architecture.

教学楼户外楼梯的空间地震效应及其加固措施

汶川地震震害调查中发现,楼梯斜板结构破坏较为严重,甚至楼梯板早于主体结构破坏出现。结合震害调查结果,针对目前中小学抗震鉴定中普遍存在的户外楼梯抗震问题,结合某中学教学楼抗震鉴定实例,讨论了楼梯斜板的空间刚度效应对整体结构抗震性能的影响。分析结果表明,楼梯斜板的空间刚度效应对整体结构抗震性能影响较大,不能忽略;楼梯斜板在地震作用下,表现为偏心受拉(压)构件,而不是原设计所认为的受弯构件,这也解释了汶川地震中楼梯间结构震害较重的原因。最后,提出了一个切实可行的楼梯斜板加固措施。
