| Abstract | ||
| Ultra-High Strength Concrete (UHPC) has been widely used in construction with many advantages such as high compressive and tensile strength, high durability, and waterproofing. This paper developed an Isogeometric analysis (IGA) for static steel UHPC composite slab analysis. High-order shear strains using refined plate theory are considered when constructing equations describing plate behavior using the Isogeometric method. Various numerical examples have been performed and compared with analytical methods from previous studies as well as with the finite element method, showing the high accuracy of the proposed method in this study. The influence of plate parameters, such as the thickness of steel and concrete layers, on displacement, was investigated in detail. | ||
