Control on Temperature Cracks of Concrete Hollow Pint-sized Block Building in China
【摘要】:正Control techniques on temperature cracks of the concrete hollow pint-sized block building(CHPBB) in China are illustrated in this paper.The reasons about temperature crack of CHPBB are investigated on the field survey.Three kinds of control techniques such as "Prevention","Resistance" and "Unrestrictionntion are evaluated.An effective control technique that synthesizes "Preve striction" to control the temperature cracks of CHPBB is submitted in this paper.The finite element method is used to analysis the temperature cracks of CHPBB in order to carry from qualitative to quantitative analysis.An example of finite element method to analyze the CHPBB is brought forth in this paper.
