4 - 98 A.6 Worked Example – Bolted connection of an angle brace in tension to a gusset 1 of 6 Made by ENM Date 04/2009 Calculation sheet Checked by JAC Date 04/2009 6. Bolted connection of an angle brace in tension to a gusset These types of connections are typical for cross bracings used both in façades and in roofs to withstand the actions of the horizontal wind load in the longitudinal axis of the single storey building. This is illustrated in SS048 [4] . SS048 [4] In order to avoid eccentricities of the loads transferred to the foundation, the angle is aligned to meet the vertical axis of the column at the base plate. The gusset plate is placed as close as possible to the major axis plane of the column. Table A.1 summarises the possible modes of failure in this connection. These verifications are shown in the following sections.
