Connections Add-on Modules

For Design of Connections

In RFEM and RSTAB, there are powerful add-on modules for design of steel and timber connections.

For example, rigid and hinged beam connections, column bases, hollow sections, and tower connections within a steel structure can be designed according to Eurocode 3.

RFEM/RSTAB Add-on Module RF-/FRAME-JOINT Pro | Frame Joints for Frames According to EC 3

RF-/FRAME-JOINT Pro Add-on Module for RFEM/RSTAB

The RF-/FRAME-JOINT Pro add‑on module creates and classifies rigid bolt connections between columns and horizontal beams according to Eurocode 3.

Optionally, it is possible to apply stiffeners, supplementary web plates, and backing plates. In addition, the module checks the geometrical feasibility of connections with respect to the size of the wrench used for tightening screws.

RFEM/RSTAB Add-on Module RF-/JOINTS Steel - DSTV | Typified Joints in Steel Structures According to EC 3

RF-/JOINTS Steel - DSTV Add-on Module for RFEM/RSTAB

The RF-/JOINTS Steel - DSTV add‑on module designs moment resisting and pinned I‑beam connections of members in compliance with the German guideline "Standardised Joints in Steel Structures". The resistances are determined according to the standard:

DIN EN 1993‑1‑8: Complete edition 2013

RFEM/RSTAB Add-on Module RF-/JOINTS Steel - Pinned | Pinned Joints According to EC 3

RF-/JOINTS Steel - Pinned Add-on Module for RFEM/RSTAB

The RF-/JOINTS Steel - Pinned add‑on module configures and designs shear connections of I‑beams according to Eurocode 3.

There are four different types available: Web cleat connection, fin plate connection, short end plate connection, and end plate connection with cleat.

RFEM/RSTAB Add-on Module RF-/JOINTS Steel - Column Base | Hinged and Restrained Column Footings According to EC 3

RF-/JOINTS Steel - Column Base Add-on Module for RFEM/RSTAB

The RF-/JOINTS Steel - Column Base add‑on module designs footings of hinged and restrained column bases according to:

EN 1993‑1‑8 (including National Annexes)

RFEM/RSTAB Add-on Module RF-/JOINTS Steel - Tower | Nominally Pinned Joints for Members Used in Lattice Towers According to EC 3

RF-/JOINTS Steel - Tower Add-on Module for RFEM/RSTAB

The RF-/JOINTS Steel - Tower add‑on module designs nominally pinned bolted connections of members used in lattice towers (connection of diagonals without gusset plate 2D/3D) according to:

EN 1993‑1‑8 (including National Annexes)

RFEM/RSTAB Add-on Module RF-/JOINTS Steel - SIKLA | Design of Sikla Joints

RF-/JOINTS Steel - SIKLA Add-on Module for RFEM/RSTAB

RF-/JOINTS Steel - SIKLA performs joint design for fastening connections produced by Sikla according to German Expert Opinion (GS) with Test Report No. K14‑6005‑3.

RFEM/RSTAB Add-on Module RF-/JOINTS Timber - Steel to Timber | Design of Indirect Timber Connections According to Eurocode 5

RF-/JOINTS Timber - Steel to Timber Add-on Module for RFEM/RSTAB

The RF-/JOINTS Timber - Steel to Timber add‑on module designs joints where timber members are indirectly connected to each other by means of steel plates. The following dowel-type fasteners are available: dowels, bolts, nails, and screws. The design is performed according to:

EN 1995‑1‑1 (including National Annexes)
ANSI/AWC NDS‑2015 (including LRFD and ADS)
- Load and Resistance Factor Design (LRFD)
- Allowable Stress Design

RFEM/RSTAB Add-on Module RF-/JOINTS Timber - Timber to Timber | Design of Direct Timber Connections According to Eurocode 5

RF-/JOINTS Timber - Timber to Timber Add-on Module for RFEM/RSTAB

The RF-/JOINTS Timber - Timber to Timber add‑on module designs joints where timber members are directly connected to each other by means of slant screws. The design is performed according to:

EN 1995‑1‑1 (including National Annexes)

RFEM/RSTAB Add-on Module RF-/LIMITS | Comparison of Results with Defined Limit State

RF-/LIMITS Add-on Module for RFEM/RSTAB

The RF-/LIMITS add‑on module analyses the load bearing capacity of members, member ends, nodes, nodal supports, and surfaces by means of a defined ultimate load capacity.

The extendable library covers timber fasteners (SIGHA, Sherpa, WÜRTH, Simpson StrongTie, KNAPP) as well as steel fasteners (standardised joints in steel structures according to EC 3, M‑connect).

RFEM/RSTAB Add-on Module RF-/HSS | Ultimate Limit State Design of Welded Joints with Hollow Cross-Section According to EC 3

RF-/HSS Add-on Module for RFEM/RSTAB

The RF-/HSS add‑on module analyzes various hollow section connections or designs an existing connection according to Eurocode 3.

It is possible to design planar and spatial truss nodes containing round, square or rectangular hollow sections.

Théâtre Marigny in Paris, France »

Roof structure

The historical building of Théâtre Marigny had to undergo renovation due to its serious defects of the roof structure which led to its closure in 2013.

The metastable equilibrium resulted from unreliable planning which did not consider the effects of assymetrical load and the suspended ceiling on the roof structure during construction in 1925.
