The option defines a Cladding, that is, a surface that lets you distribute planar, linear and concentrated loads on bars, panels and supports. This object can considerably facilitate generating loads; it allows you defining real structure objects that do not participate in the load capacity of a structure, such as panel walls and roofing. You can apply planar loads (uniform or not uniform, defined on any contour or object), linear (defined by 2 points or on edges) and concentrated (force at the point) to claddings. You can also use claddings when(which is equivalent to defining a uniform planar load on an object) and 3D snow and wind loads are generated. A finite element mesh is not generated on a cladding; it is an auxiliary object for defining loads.
The dialog has the following parts:
At the top of the dialog:
The list field displays 3 available types of load distribution based on the load direction:
A surface object is generated in the form of a face with defined cladding. A surface is defined in the same manner as a panel (by indicating an internal point or the list of linear objects).
You can also define a cladding by selecting the Geometry menu > Claddings.
Loads from claddings are distributed on all objects in the contour and plane of a cladding:
You can select objects that lie in the plane of a cladding (or of a panel for which the trapezoidal and triangular distribution is selected in a calculation model) and do not carry loads. In a real structure, these can be elements of roof bracing that do not carry the load transferred from the roofing. You can select objects using either of the following ways:
Click (...) to open the Selection dialog.
You can define a surface by assigning cladding to a face-type object for the following structure types: bar structures and shell structures. It is assumed that for volumetric structures the face object behaves like a face of a volumetric structure; you cannot define loaded surfaces on such an object. All types of loads (planar, linear, and nodal) can be applied to a cladding, except for 2 types of planar loads: hydrostatic pressure and thermal loads.
