Shear key can be constructed from concrete as in precast constructions, residential building basement or manufactured from steel such as in the case of steel column base plate, and sometimes steel reinforcement is used to play shear key …

Design of Shear key: If the wall is not safe against sliding, then a shear key is to be provided. It is provided either below the stem or at the end of heel. It should not be provided at the end of toe. If shear key is provided, then it should be designed taking the effect of passive pressure.

Aug 22, 2023 · Base plate design as per IS800 codal provisions, Shear key is provided to increase the resistance to sliding. The shear key is generally an extension of the vertical stem and extends below the bottom of the base to help reducing the thickness of the anchor bolts by absorbing the shear force.

The document shows design drawings for a 200x200mm shear key with a depth of 100mm that is placed between a pedestal and a base plate. The shear key has openings on both sides to allow shear transfer between the pedestal and base plate.

... key design and sample preparation Four types of shear keys, that is, trapezoidal, semispherical, dome and wave, are assessed. Figure 1 shows the dimensions and the render of the concrete...

The shear key is a part of the structural element mostly used to make the structure stable against the lateral loads. Depending on the type of construction and nature of the loading, the application of shear is different. Mostly the shear keys are constructed between two structural elements.

The document summarizes the design of a shear key below a column base plate. It calculates the shear capacities along longitudinal and transverse directions considering concrete crushing strength, weld strength, concrete tension capacity, and shear capacity of the key section.

Shear Key Design - Free download as PDF File (.pdf), Text File (.txt) or read online for free. The document describes the design of shear keys for three different column groups.

These keys are designed as a series of overlapping male-female connections along the joints, see Figure 1 and 2. In order to ensure a good accuracy of fit in the dry joint, the elements are match cast. Figure 1 – 3D-sketch of two elements, illustrating the …

Shear keys play an import role in limiting the excessive displacement of bridge superstructures during catastrophic events. However, rigid shear keys often damage, leading to girders falling...
