Taking beam lower flange of SPA-1 as example, the simulation gives deformation of weld region, for small deformation, the result enlarged 40 folds is shown in Fig. 5 (a)13s (b)100s (c)1000s (d)1500s Fig.5 Deformation of SPA-1 weld region Fig.4 Beam lower flange temperature field of SPA-1 changing with time Material experiment and loading system Looking tri-linear curve as stress-strain model, so values for key points (strain yield point, limit point and failure point) are determined as follows: Strain is 0.00146, 0.198, 0.316, stress is 299.2 N/mm2, 420.6 N/mm2, 357.5 N/mm2.

Using Hertz contact force model which is established on the basis of elasticity theory to calculate the contact force[8], energy consumption is regarded as caused by material damping in the process of contact, although this method is an approximate analysis method, it is easy and convenient to use.
