  Loads and results are as abbove. So I want to ask you guys that why the top area of geometry is almostly stress-free when I give 15Mpa to the top face

  This is because the external forces are balanced by forces developed inside the material, which basically tends to oppose the elongation effect, causing the equilibrium state. What the image tells you is where the part is most stressed to balance the pressure load applied on the top.
  
  Refer to the Ansys theory manual for more details:
