Direction of loads

Point force load

Point force load defined in a node or on a 1D member can be acting in the following directions:

global co-ordinate system

Both point force load in node and point force load on 1D member can be defined to act in the direction of the global co-ordinate system.

local co-ordinate system of node

Point force load in node can be acting in the direction of local co-ordinate system of the node.

local co-ordinate system of beam

Point force load on 1D member can be acting in the direction of local co-ordinate system of the 1D member.

Line force load

Distributed load on a 1D member can be acting in the following directions:

global co-ordinate system	$image\Load_LineForce_GCS.gif$
projection in the global co-ordinate system	$image\Load_LineForce_GCS_projection.gif$
local co-ordinate system of beam	$image\Load_LineForce_LCS.gif$

Moment load (point and line)

global co-ordinate system

Both point moment load in node, point moment load on 1D member, and line moment load on 1D member can be defined to act in the direction of the global co-ordinate system.

local co-ordinate system of node

Point moment load in node can be acting in the direction of local co-ordinate system of the node.

local co-ordinate system of beam

Both point and line moment load on 1D member can be acting in the direction of local co-ordinate system of the 1D member.

Point displacement load

global co-ordinate system

Point displacement load in node can be acting in the direction of the global co-ordinate system.

local co-ordinate system of node

Point displacement load in node can be acting in the direction of local co-ordinate system of the node.

local co-ordinate system of beam

Point displacement load on 1D member can be acting ONLY in the direction of the local co-ordinate system of the 1D member.

Line displacement load

Line displacement load can be defined ONLY in the direction of local co-ordinate system of the 1D member.
