Calculation of Shear Fatique Life of P.P.C.Beams Xiao Guanghong,Jiang Bingzhang,Zhang Quiling 1995, 14(4): 5-9.  Abstract ( )   Based on the test results,this paper analyses shear fatique behavior and shear fatique failure char-acteristics of partially pretressed concrete beams and srudies shear fatique strength and calculatingmethed of shear fatique capacity of P.P.C. beams. Test results shown that beams were able to sustainload for over one million cycles following initial stirrup fracture,t is not proper that the fracrure of thefirst stirrup is regarded as failure of beams and further contribution to shear capacity would be consid-ered.

Analysis of Temperature Curling Stress on Concrete Pavement Zhou Huxin,Chen Rongsheng,He Zhaoyi 1995, 14(4): 28-35.  Abstract ( )   This paper studies westergaard and finite-element method to calculate curling stress. Using finite-element program CTO5, curling stress on concrete pavement is calculated. The relationship between thecurl ing stress and subgrade parameters is obtained,and the effect of the slab length and width on thecurling stress is analyed,the results have practical value to the design and construction of concrete pave-ment.

Study on the Field Determination of Thermal Parameters of Rock Mass Chen Xichang,Zeng Jianquan 1995, 14(4): 62-68.  Abstract ( )   In this paper,according to the heterogeneous the rmal characteristics of the foundation rock mass,based on the theory of heat conduction and the principle of theimal expansion and shrinkage,the fieldtestings are conducted to measure the temperature and the deformation of the rock mass. Thus the ther-mal conductivity and the linear expansion coefficient are calculated inversely,and a computational pro-gram is made to deal with the data,The results show that the method is of high precisim and is muchconvenient, and can provide the reliable and more reasonable data References | Related Articles | Metrics
