Flexural behavior of precast concrete sandwich wall panels (PCSW) can be divided into one way or two-way according to their aspect ratio. A total of five specimens were tested to find out the effects of design direction of shear connectors and the type of insulation on flexural behavior of PCSW. Design of shear connector in two-way direction has better performance in terms of initial stiffness than those of design of shear connector in one-way direction. Also, the specimens with extruded polystyrene (XPS) foam has higher performance in terms of initial stiffness and ultimate strength than those of the specimens with for expanded polystyrene (EPS) foam.
