Roof struts and ties.
The part of the structure that has a tensile force acting on it is called a tie and the part that has a compressive force acting on it is called a strut.
A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof trusses usually occur at regular intervals linked by longitudinal timbers such as purlins the space between each truss is known as a bay.
The beam is held in position by a steel rod.
The weight of the beam is stretching the rod tensile force.

It is an industry convention that the arrows are shown pulling in on themselves.
Tension members in trusses are called ties and these are members which are being stretched.
The part of the structure that has a tensile force acting on it is called a tie and the part that has a compressive force acting on it is called a strut.
The struts are needed in the roof frame to transfer the loads from underpurlins and other beams to the load bearing walls.
They should have anti slip blocks where necessary to prevent them sliding horizontally.
All structures have forces acting on them.
Struts should be adequately supported over studs in timber walls.
