in this tutorial video you will learn how tu use CBFEM with IDEA Statica software to make connections to design and code checiking of a structural steel joint, case stady of a connection of tubular 3D Frame.

Principles of CBFEM method.
CBFEM - how it works, code compliance, validation and verification
Component Based Finite Element Method (CBFEM) is a synergy of the Component Method and Finite Element analysis.
CBFEM is a unique method for the design and code-check of steel connections, members, and anchoring. It can be used for the majority of joints, anchoring, and details with various topologies.
Component Based Finite Element Method (CBFEM) method is:
• General enough to be usable for most of the joints, footings, and details in engineering practice.
• Simple and fast enough in daily practice to provide results in a time comparable to current methods and tools.
• Comprehensive enough to provide structural engineers with clear information about joint behavior, stress, strain, reserves of individual components, and about overall safety and reliability.
The check of a joint in a standard component based method and in the CBFEM used in IDEA StatiCa Connection is based on the check of all parts of the joint – the components. Components can be bolts, anchors, welds, plates, and concrete at the footing.
CBFEM splits the whole joint into above mentioned separated components. Then the analysis model is created automatically by the software from each component.

Cable-Stayed Bridge modeled in Autodesk structural bridge design

A cable-stayed bridge has one or more towers (or pylons), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
Comparison with suspension bridge
In cable-stayed bridges, the towers are the primary load-bearing structures that transmit the bridge loads to the ground. A cantilever approach is often used to support the bridge deck near the towers, but lengths further from them are supported by cables running directly to the towers. That has the disadvantage, unlike for the suspension bridge, that the cables pull to the sides as opposed to directly up, which requires the bridge deck to be stronger to resist the resulting horizontal compression loads, but it has the advantage of not requiring firm anchorages to resist the horizontal pull of the main cables of the suspension bridge. By design, all static horizontal forces of the cable-stayed bridge are balanced so that the supporting towers do not tend to tilt or slide and so must only resist horizontal forces from the live loads.
in this tutorial video we are juste showcasing the process of modeling of cable-stayed bridge in using AutoCAD and Autodesk structural bridge

in this tutorial video we showcasing the fast process for modeling and design a pedestrian or suspension foot bridge in using AutoCAD 3D for the first step after, the model is exported to Autodesk structural bridge design for design and Analysis because is a fast and suitable method for complex bridge modeling and design, after to watch this video, you will be able to get a deep knowledge for complexe bridge structure modeling and design.

For information:
Suspension bridge
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s
the suspension cables must be anchored at each end of the bridge, since any load applied to the bridge is transformed into tension in these main cables

In the family of bridge systems the cable supported bridges are distinguished by their ability to overcome large spans.At present, cable supported bridges are enabled for spans in the range from 200 m to 2000 m (and beyond), thus coveringapproximately 90 per cent of the present span range.
(1) the deck (or stiffening girder);(2) the cable system supporting the deck;(3) the pylons (or towers) supporting the cable system;(4) the anchor blocks (or anchor piers) supporting the cable system vertically and horizontally, or only vertically, at theextreme ends.
Footbridge
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians.[1] While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land
For rural communities in the developing world, a footbridge may be a community's only access to medical clinics, schools, businesses and markets. Simple suspension bridge designs have been developed to be sustainable and easily constructed in such areas using only local materials and labor.
