In this paper, dissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel is investigated experimentally. For this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. The effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

Soil exists mainly in unsaturated conditions. Therefore, accurate prediction of the soil shear strength for conditions also becomes equally important geotechnical design earth structures. This study primarily investigates effect moisture content on its strength. The characteristics silica sands with different grain sizes were studied using modified triaxial apparatus and analytical methods. For...

An innovative type called "butterfly-shaped links steel plate shear wall (BLSPSW)" was proposed as a lateral load resisting system. In this novel system, by creating butterfly-shaped links in the four sides of the web plate, the lateral load resisting mechanism is not the development of a diagonal tension field on the web plate (similar to Conventional SPSWs), but the capacity of the system is ...
