What is local and global axis in staad pro?
Local X in STAAD is always in longitudinal dir. of member and Y and Z are minor and major axis. Global axis in STAAD you can change by rotating the member OR by changing the setting by Y up OR Z up.
What are the coordinate system in staad?
This coordinate system is a rectangular coordinate system (X, Y, Z) which follows the orthogonal right hand rule. This coordinate system may be used to define the joint locations and loading directions.
What is global and local coordinate?
Global coordinate system – corresponds to the entire body and is used to define nodes in the entire body. Local coordinate system – corresponds to a particular element in the body , and the numbering is done to that particular element neglecting the entire body . ocabanga44 and 15 more users found this answer helpful.
What is local coordinate system?
A local coordinate system (LCS) is a set of x, y and z axes associated with each node in the model. It is often preferable to use a local coordinate system for assigning constraints and loads to simplify the constraint or load to one direction.
What is difference between local and global axes?
By convention, we distinguish the global axes from the local axes by using upper case for global and lower case for local: the global directions are referred to as X,Y,Z or GX,GY,GZ, and the local object directions as x,y,z or Lx,Ly,Lz (we may also use the body-specific form for local axes, such as the vessel frame …
What is Gy in staad pro?
Partial Surface Trapezoidal Load GX, GY and GZ represent the global X, Y, and Z directions along which the pressure may be applied. For element pressure (force per unit area), these values represent the coordinates of the rectangular boundary on which the pressure is applied.
Which coordinate system is used to define structure?
In two dimensions, the most common system is the Cartesian (after René Descartes) system. Points are designated by their distance along a horizontal (x) and vertical (y) axis from a reference point, the origin, designated (0, 0). Cartesian coordinates also can be used for three (or more) dimensions.
What is the difference between the global and local Axis?
Local axis is the axis of member and global axis is the axis of entire structure.

What are global coordinates?
Global Coordinate System Coordinate systems are considered right if the Y axis is formed by rotating the X axis counter-clockwise when looking from the end of the Z axis at a 90 degree angle. In this global coordinate system, the Z axis is always directed upward.
What are the different types of coordinate systems used in Staad?
STAAD uses two types of coordinate systems to define the structure geometry and loading patterns. The Global coordinate system is an arbitrary coordinate system in space which is utilized to specify the overall geometry & loading pattern of the structure.
What is a local coordinate system?
A Local coordinate system is associated with each member (or element) and is utilized in MEMBER END FORCE output or local load specification. Each axis of the local orthogonal coordinate system is also based on the right hand rule. Note that the local coordinate system is always rectangular.
What is the right hand rule for local coordinate system?
The right hand rule is followed to determine the positive direction of the Y axis. A Local coordinate system is associated with each member (or element) and is utilized in MEMBER END FORCE output or local load specification. Each axis of the local orthogonal coordinate system is also based on the right hand rule.
