Fracture positions were found to locate at the 3A21 base materials if conventional samples with constant width were used, so a specially designed sample with a narrow “neck” at the weld as shown in Figure 2 was utilized to ensure that all the specimens will fracure in the zone of weld, so that we can analyze the effect of welding parameters on the strength of the weld.
A method for choosing welding parameters is proposed based on the value v/w. 5 Acknowledgements This work is supported by National Science and Technology Major Project (2012ZX04008011).

The reason may be due to that no chemical reactions between different compositions including tar, clay and pitch occurred at this low temperature; in other word, no harmful materials were formed.
This work is helpful for understanding the possible property transition of the tap-hole clay in the tap hole and also provides research method for other composite materials.

In the SeismoStruct, con_ma and stl_mp were used as the material models.
In the OpenSEES, Concrete 02 and Steel 01 were used as the material models: the former construct a uniaxial concrete material object with tensile strength and linear tension softening whereas the latter is a uniaxial bilinear steel material object with kinematic hardening.
These and material parameters were utilized in the analytical works performed on the five-story frames.
