three dimensioned finite element analysis were conducted on concrete block paving. in order to verify the calculated results, an experimental case study was analyzed. good agreement was observed between the measured and the calculated results. based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement wh...

Some Problems on High Strength Concrete for Prestressing by Kanji YAMAZAKI (Research Laboratory of Nihon Cement Co., Ltd., Tokyo) This paper describes some problems on high strength concrete studied in our laboratory in recent years. Summary of this report is as follows: (1) In order to make high strength concrete for prestressing, it is necessary to lower the water-cement ratio. But, in the ca...

T h e frict,ion behavior of rubber materials on various contact surfaces is strongly affected by the contact pressure and the relative sliding velocity. Based on a great number of experiment,^ of rubber block moving on concrete surfaces. a friction law is present,ed in this paper. It is characterized b~ a dependence on contact pressure and sliding velocity. The identification of the required pa...
