| 中文摘要: |
| 伸缩缝间距与温度应力及混凝土收缩产生的应力关系密切,<混凝土结构设计规范(GB50010-2002)>给出的钢筋混凝土框架伸缩缝间距取值比较原则化,如能保证温度应力及混凝土收缩应力不大于混凝土的抗拉能力,保证混凝土不开裂,则可确定伸缩缝间距.以单层框架为例,通过理论分析,计算出框架结构的温度应力,这将有助于伸缩缝间距的计算. |
| 英文摘要: |
| The values of expansion joint spacing of reinforced concrete structures which given by some standards are closely related to temperature stress and shrinkage stress of reinforced concrete.If the stresses caused by temperature and shrinkage are less than the allowable stresses,reinforced concrete frame Structures will have no cracks,with the values of expansion joint spacing taken into consideration.A calculating formula of temperature stress for one floor reinforced concrete frame structures were presented by theory analysis,it contribute to calculating of the values of expansion joint spacing. |
