As a result of the advantages of the steel fiber reinforced concrete pavement structure, which includes high strength, high stiffness, and high stability, a large number of steel fiber concrete pavements will be used for highway construction in China. As a result, numerous cracks develop, which significantly reduces the life of the road; therefore, the study of the jointing problem is vital. As concrete research on the influence of the load transfer capacity and service life of prefabricated steel fiber reinforced concrete joints on the structural design and use function of the whole and pavement panels, the paper proposes two joint forms, tongue-and-groove and overlap. Using experiments and software, the stress and reflection of prefabricated road panels of the two joint forms are analyzed for different axial loads. The analysis reveals that the maximum tensile stress, shear stress, and deflection of the precast panels of both joint forms increase linearly as the axle load of the vehicle increases, while the service life decreases relatively. The load transfer capacity is independent of the axle load magnitude, and the load transfer capacity difference between the two types of joints is minimal and excellent. [ABSTRACT FROM AUTHOR]

The article presents comments of the author on a paper on the iron and steel industry by Kuei-Sheng Chang. He has adopted a useful approach in analyzing the locational pattern in terms of major nuclei associated with secondary centers in the various regions in China. Based on my current research, however, I fear that the picture of Communist China's iron and steel industry that emerges in this paper is one exaggerated achievement and it is likely to mislead some readers who have not followed recent developments.

The article presents a response of the author on comments made by scholar Theodore Shabad on his paper on the iron and steel industry in China. The study of any important aspect of the industrial geography of Communist China involves difficulties and pitfalls seldom encountered in other endeavors. I fully understand what Shabad means by the frustrating process he himself is now engaged in. Aware of limitations of individual effort, from the outset I choose only a limited objective to offer a locational analysis of the major nuclei in the emerging pattern and their effect upon the development of secondary centers in the various regions of China.
