RISAFloor has the capability to design wood I-Joists based on tables provided by the manufacturer, or provided by you. When modeling beams in RISAFloor, choose the Wood Product material, and choose a joist manufacturer from the shape group.
RISAFoundation now has the ability to automatically generate a circular slab with just a few easy clicks. Using the generator the program will create the mat slab and tank loading all in one easy step. Go to the Insert menu and select "Circular Foundation".
In standalone RISA-3D models (those not integrated from RISAFloor), Semi-Rigid diaphragms cannot be directly defined. Only the Rigid diaphragm type is available by default. To create a semi-rigid diaphragm in a standalone RISA-3D model, users must define plate elements manually. If you’re dealing...
In order to understand the interaction between plates and members it is important that you know the basics of Physical Members and Plate Connectivity. Remember that plates only connect to other elements at their corners, and you will instantly recognize why the model below will not work as intended.
In RISA-3D and RISAFloor, the entire NDS species list is available as well as glulam materials but you may need to design a wood product that is not available in the program.
To best understand how plates interact with each other you must first understand the concept of Physical Members. The important thing to keep in mind is that plates are not physical members. A plate is defined using either three or four joints, and it only connects to other plates at those joints....
When you have a deep column, it is necessary to model the beam so that it connects to the face of the column. This results in an eccentricity at the joint. RISA-3D offers two ways to model this eccentricity.
The customizable toolbar is a new feature in RISAFloor. It’s really useful and you may have overlooked it. You’ll find all of your familiar buttons as well some new buttons which make reviewing your model and results easier.
There are four different values for Unbraced lengths in RISA-3D, RISA-2D and RISAFloor. Two are for axial calculations and two are for bending calculations.
