Introduction High strength steels have an increasingly important role in engineering applications, especially in the vehicle and transportation industry, where the producers are faced with the challenges of strict requirements for lower CO2 emission, and there is customer demand for lower operational costs.
However, the determination of the right welding technology, including the optimal process window, may still cause difficulties for welding engineers [1-7].

However, the shear lag effects in bottom slab of the PC box girder with corrugated steel webs are almost similar to those of the conventional PC box girder with concrete webs, no matter what kind of vertical bending moment the cross section is subjected to Introduction The phenomenon of “shear lag” in the conventional Prestressed Concrete (PC) box girder bridge subjected to bending moment, i.e. the non-uniformity of the transverse distribution of the longitudinal normal stresses on slabs’ section that resulted from their in-plane shear deformations, had attracted much attention and been researched thoroughly, and also the concept of effective flange width was introduced to the engineering practices1.
In all, the current understandings on the shear lag effect of the PC box girder with corrugated steel webs are still not clear enough to reach some practicable guidelines for engineering design.
The coefficient of effective flange width is a practical evaluation of the shear lag effect in engineering design6, 7.

Proceedings of the Institution of Mechanical Engineers, Part N: Journal ofNanoengineering and Nanosystems. 225 (2011) 17-22. ] studied the impact of carbon nanotubes on the flexural properties of cement-based materials, and found that 0.25%, 0.5% and 0.75% MWNTs addition increased the flexural strength of cement by 30.76%, 37.93% and 43.75%, respectively.
These studies provided important theoretical basis for the application which MWNTs cement-based composites were used as stress sensors in civil engineering.
