Joint Design

In the event that the ability of the column web to resist the applied shear is exceeded, then an appropriate web plate (doubler) will be designed. RAM Frame will only provide a web plate where the panel zone shear capacity of the column is exceeded by more than 1%. If a web plate is required, then where the capacity of a column’s flanges and web (including the contribution of the web plate) is exceeded for any of the concentrated force checks, RAM will attempt to increase the thickness of the web plate to increase the columns capacity. If an adequate web plate cannot be designed, then a stiffener will be used and the web plate will once again only be sized for the panel zone shear. Where no web plate is required for panel zone shear check, but the capacity of the column flanges and web is exceeded for any of the concentrated force checks, RAM will provide a stiffener to meet the code requirements. The design of the web plate and stiffeners at a joint is based on the criteria provided by the engineer through the dialog displayed by invoking the Criteria-Joints command.
