Building a Model Guideline
Typical steps for the creation of a building model are outlined below. The forms (dialog) for the first three steps will automatically appear when a new project is defined. The best way to learn how to build a new model is to go through our ...
Modelling, Analysis & Design Flowchart
With reference to the flow chart, click on the links below for details. 1. Build the Model ► Building Model Check 2. Derive Beam Loads using the "Yield Line" (tributary area) approach. 2a. FE Load Decomposition 3. Run the general Building ...
Yield Line and FE Load Decomposition with Example
For your best understanding to this topic, it is best to refer and relate to Modelling, Analysis & Design Flowchart before proceeding with this article. There are two methods to calculate slab loads onto supporting beams : 1. Derive Beam Loads using ...
How to model a continuous beams with varying depth
Modelling continuous beams with different depths can be done with reference to this Video. The summary of steps are : Model axes to be used as insertion points for the beams. Model separate beams using the e-z (h-top) property to adjust the elevation ...
Working with Steel Truss
Auto-generated steel trusses of any shape (e.g. Pratt, Warren, mono-pitched, duo-pitched truss). The trusses can be easily moved and copied to another location. Defining a New Truss Before inserting a truss, there must have supports created for ...
Working with Brace
Defining a New Brace In order to define new braces follow the below steps: Click on the "Brace" button from "Modelling" tab or you can use command line at right bottom corner. Pick two consecutive columns or beams. Brace dialog will be loaded. ...
Working with Purlins
Defining a New Purlin Before inserting purlins, trusses/beams must be defined. To define purlins: Click on the "Purlin" button from "Modeling" ribbon or you can use command line at right bottom corner. Select first truss/beam then select last ...
Define Wall/Column Span Loads
User-defined varying distributed lateral loads can be applied to the individual column and wall member. The span load applied maybe used to simulate : Soil Pressure on basement wall Hydrostatic load As an alternative to defining wind load (other ...
How to model a Transfer Beam
Before proceeding with the modelling of the transfer beam, it is important to understand how the physical model translate to an analytical model when building analysis is performed. The physical model is what you see on the modelling screen where all ...
How to model a Transfer Slab
The steps of modelling a transfer plate is similar to that of modelling a flat slab system. Model the supporting column and walls in the transfer storey Model the transfer slabs in the transfer storey Model the discontinuous walls or columns in the ...
How to model slanting / inclined column
A column can only be inserted at the intersection of 2 axes which forms a node or joint. When a column is inserted, the top and bottom of the column will use the same node. To model a slanting or inclined column, an additional node (intersection of ...
How to model slanting / inclined beam
When a beam is modeled, it is by default created horizontally at the top of the active storey in view. The elevation of the beam can be changed using the del z boxes for each end of the beam in the Beam Properties > 3D tab. Method 1 : Input delZ ...
How to model inclined / sloping slab
To create a sloping slab panel you must first define a Plane to align it to. Once the plane has been defined the slab can simply be moved into the new plane. This method can also be used to model inclined / slanting beams. We will use a simple table ...
How to raise or drop a beam in elevation
By default, the top of the beam is always assumed to be atop of the storey in which the beam is modelled. To change the elevation of the beam, i.e. to lower or raise it from default, there are 2 methods : Use e-z input in the Beam Properties > ...
Working with Slab Openings/ Drops
Slab Opening Properties "Slab Opening Properties" will be loaded when the "Slab Opening" option in the "Modelling" ribbon is selected. A new slab opening can be defined by arranging the fields in the form and then by clicking the insertion ...
Working with Slab Strips
Slab Strip Properties Slab Strip The "Slab Strip Properties" will be loaded when the "Slab Strip" option in the "Modelling" ribbon is selected. The "Slab Strip Properties" has two tabs only. After arranging the fields for the slab strip form, a new ...
Support Types
Support Types Each of the Six Degree of Freedoms (DOF) at the bottom node of the columns can be restrained or unrestrained. Furthermore, each of these DOF can be assigned torsional or axial springs whose spring constants are to be determined by the ...
Slab Additional Loads Library
The “Slab Additional Loads Library” is used to create/edit the additional dead loads selectable from the drop down menu on the “Slab Properties” dialog. "Slab Additional Loads Library" will be loaded when this option in the "Building Setout" ...
Beam Wall Loads Library
The “Beam Wall Loads Library ” is used to create/edit the standard wall loads selectable from the drop down menu on the “Edit Beam Wall Load” dialog. "Beam Wall Loads Library" will be loaded when "Partition Wall Loads " in the "Loading" pulldown is ...
Temperature Loads
Define Temperature Difference User-defined temperature differences can be assigned to individual, or multiple columns, walls and beams in the model. An “Axial” temperature load causes the entire member to change in temperature by the specified ...
Structural Modelling Overview
Techniques for member creation and loading are described in this section. Also described here are those other modelling related functions contained on the “Member” pulldown. Additional modelling related topics can be found in the preceding Graphic ...
