| [en] Parallel to the investigation in the second generation of Eurocodes, the Chinese design standards are also updated. At 01/12/2016, a new Chinese Code for the design of composite structures JGJ138-2016 was put in practice to replace the old JGJ138-2001. Benefit from the vast experience of composite structure applications blooming recently in Chinese, the new code covers much wider topics and is more comparable to Eurocodes 4. Generally, both codes cover topics of composite beams and columns, composite slabs and composite connections. However, JGJ138-2016 covers also the design of composite shear walls, while Eurocode 4 considers more about durability and time effects.
It is necessary to compare the materials used for both of codes. In this article, it covers comparison of the mechanic properties such as elastic modulus, characteristic strength and design strength. The analysis includes concrete, reinforcement, and structural steel. The main comparison is the design procedure of composite columns. The application range of the codes will be pointed out first. Both codes allow the design of concrete encased sections and concrete filled rectangular and circular tubes. However different limitations on cross-section sizes and materials can be found. Eurocode 4 represents three different design methods: the simplified method for centric loading, based on the buckling curves; the general method based on 2nd order calculation for action effects and N-M interaction for the determination of resistances; as well as the non-linear method based on stress-strain limitation of material and FE-Analysis. Chinese code gives a simplified method of the calculation of column resistance for centric and eccentric loading. Also the impact of second-order effect are to proof if needed. According to the EN1994-1-1 the impact of creep is to consider for the denervation of the bending stiffness and for ideal buckling resistance and non-dimensional slenderness. JGJ138-2016 do not consider impact of creep for the design. Besides, JGJ138-2016 includes also design for seismic situation. The axial cross-section resistance and normal force-moment interaction curves (N-M curves) will be compared through theoretical analysis and parameter studies. JGJ138-2016 considers mainly transversal shear resistances, while Eurocode 4 further considers shear connection, load introduction and longitudinal shear outside the areas of load introduction. The design shear resistance will be compared in general and within parameter study. | |
