Design of Slab Base for a Column Compression Member Design and Welded Connection
Introduction Welcome back to the channel! In this presentation, we will discuss the design of design of a slab base for a column. Key parameters for the design include length, length, thickness, and compression strength. We will also cover the design of the welded connection between the slab base and the column. column.

Design Procedure To design a slab base for a column, we start by by noting down the properties of the section from from steel table. The thickness of the flange (tf) is 11.6 mm and the and the thickness of the web (tw) is 8.3 mm. We calculate the bearing strength of the concrete using the formula: bearing strength = 0.45 * fck Next, we determine the required area of the base using the formula: area = factor load / bearing strength.

Area Calculation The factor load (p) is given as 1000 kN/m2. Using this value, we calculate the area to be provided for the base. The calculated area is 11.31 m2. We then determine the dimensions of the base by considering the length (l) and width (b) requirements. Photo by Pexels Photo by Pexels
Base Dimensions The length (l) of the base is determined as 390 mm. The width (b) of the base is determined as 290 mm. We confirm that the area of the base meets the requirements. These dimensions will be used for the construction of the slab base for the column. Photo by Pexels Photo by Pexels
Welded Connection Design In addition to the design of the slab base, we also need to design the welded connection between the base and the column. The length of the fillet weld is determined as 1493 mm. The size of the weld is calculated based on the thickness of the thicker part, which is 12 mm. Based on the shape of the weld, the minimum size is determined as 5 mm and the maximum size as 6.8 mm. Photo by Pexels Photo by Pexels
Final Design The final design includes a slab base with dimensions of 390 mm (length) and 290 mm (width). The welded connection between the base and the column has a fillet weld size of 6 mm. This design ensures structural stability and meets the required design criteria. Thank you for watching! Photo by Pexels Photo by Pexels
