Steel Simple Connection Designer

CADS Steel Simple Connection Designer is a program for checking of simple connections based on BS EN 1993:2005 – Design of Steel structures – Part 1-8 Design of joints and SCI P358 – Joints in steel construction: Simple joints to Eurocode 3.

The following types of connections can be checked by this application:

Beam-to-beam connection (end plate or fin plate)
Beam-to-column connection (end plate or fin plate)
Column splice (bearing or non-bearing)
Column base plate
Beam-to-beam splice

According to BS EN 1993-1-8:2005 nominally pinned joints, checks of the joint are made to ensure it;

Should be capable of transmitting the internal forces, without developing significant moments which might adversely affect the members or the structure as a whole;
Should be capable of accepting the resulting rotations under the design loads.
Can provide the directional restraint to members which has been assumed in the member design;
Will have sufficient robustness to satisfy the structural integrity requirements (tying resistance).

Verification checks, below, are also made of the strength of a nominally pinned joint;

To ensure that the joint is detailed such that it develops only nominal moments which do not adversely affect the members or the joint itself. The joint should be detailed so that it behaves in a ductile manner;
To identifying the load path through the joint i.e. from the beam to the supporting member;
To check the resistance of each component.

Bolt Group Analysis

CADS Bolt Group Analysis is a software application to calculate the forces in a bolted connection. The program uses the elastic method to calculate and check the force distribution in a connection subjected to vertical, horizontal, inclined, and torsional loading.

Beam-to-beam splice connection

In beam-to-beam splice connection the forces are transferred through the cover plates and bolts. The web splice plates and bolts are typically responsible for transferring vertical shear forces between connected beam segments. The flange plates and associated bolts transfer the tension and compression resulting from the bending moment at the splice location, like the flanges in the main beam.

Column-to-column splice connection

There are two types of column splice connection:
Top image: Bearing type (with or without division plate);

Bottom image: Non-bearing type.

Timber Connection Designer

Calculation

Calculations are in accordance with BS EN 1995-1-1:2004+A2:2014 – Design of timber structures –
Part 1-1 General Common rules and rules for buildings for UK National Annex.
Verifies the capacity of the connection, connected members, gusset plates and fasteners.

Input

Software supports different types of connections splice, apex/corner, and intermediate (with and without gusset plates);
Different types of fasteners are supported based on connection types;
Member properties such as material, cross-section and its orientation can be defined;
Allows entry of factored axial, shear and moment loading along with the load duration.

Output

3D and 2D preview of the timber connection with loading details;
Customisable output with 3 levels of output details;
MS Word and PDF export of output reports.
