Abstract:Following the sophistication in the technology of casting and the advancing of the analysis program, caststeel joints have been widely used in all types of new structural systems and complex structural connections. Combining with the design of caststeel joints for Bicycle Training Centre of Beijng Lucheng Physical Training Shcool, the formations of cast steel joints and their characteristics are introduced, the performance of caststeel material is analyzed, proofs for the rationale selection ofcaststeel material are offered. Using the grade 4 strength theory as strength estimation methodology, it helps to provide means of confirming the structure strength, and to analyze the distribution of structure strength in caststeel joints. Furthermore, through the understanding of the distribution of its strength, it facilitates the handling of the detail construction of casting connection is presented. With reference to technical documents published both inside and outside China, and with the realistic situation of the construction detail for this project, information such as the standard of inspection is provided.
