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 reference. Slab Opening Dimensions (b1, b2) Horizontal ("b1") and vertical ("b2") dimensions of the […]

This function can specify a region and insert a space truss parametrically. You can control parameters such as cell size, number of rows and columns, curvature and more. Inserting a Space Truss To insert a steel space truss: 1. Pick the Space Truss command on the Modeling > Steel Members ribbon tab. 2. Draw a […]

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 user. In order to create Support Types to be assigned to bottom node […]

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" pulldown is selected. The library consists of 3 tables: “Material Library” – this is a list of various slab […]

Program provides some modelling replication/ manipulation for ease of modelling.  Copy/ Move Member Select a member (e.g. frame member) or multiple members.  Right-click and select Copy or Move command.  Pick the reference point on screen and pick the destination point which the member(s) will be copied or moved.         Copy/Move Special Command Copy/ […]

Steel Dome Structure can be easily created using the "Steel Dome" function in the "Modelling" tab. Defining a New Dome To define a steel dome : Go to "Modelling" tab > Steel Dome Select the dome insertion point diagonally (select the diameter of the dome). Double click the dome to access its properties to adjust the parameters.   […]

To create a irregular shape concrete column, you use Polyline Column Editor.  After defining a rectangular column at an intersection, this column can be converted into a polyline column by : Select the Column Click "Polyline Column Editor" icon in the top Column Ribbon Alternatively, right-click to expose the context menu >  Choose "Polyline Column […]

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 than the default method of application to the floor diaphragm)  The currently specified  Load Combinations must include […]

The measure command in ProtaStructure is significantly improved so that you can snap to any 2D and 3D points, including line intersections, solid object vertices, extensions, intelligent element points, axis intersections, and so on, and measure the distance between them. The measure command will immediately mark the points with coordinate labels and provide information on […]

Defining a New Brace In order to define new braces follow the below steps:  Click on the "Brace" button from "Modelling" ribbon or you can use command line at right bottom corner.                                      Pick two consecutive columns or beams.  Brace […]
