MATERIAL EXPERIMENTAL STUDY AND FINITE-ELEMENT ANALYSIS OF NEW ENERGY-SAVING WALL STRUCTURE

摘要：

The workability of the expandable polystyrene (EPS) lightweight concrete is quantitatively evaluated by the thermal conductivity (R), the strength (P), and the volume density (ρ) (R:≤0.10w/(m·K)～0.14w/(m·K); P:≥ 0.3MPa;ρ:350kg/m3～500kg/m3). The reasonable mixture ratio presented in this paper meets various requirements for workability. Based on the experimental results, detailed finite element models of EPS new energy-saving wall structural members are established to determine mechanical performance of wall structure. It is found that the maximum stress is reasonably located in short columns of concrete skeleton, and on the whole, the stress distribution of wall members is uniform. Results show that the new energy-saving wall structure has good mechanical properties, and an excellent overall performance.
