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.

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 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-/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 - 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-/LIMITS | Comparison of Results with Defined Limit State

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

The RF-/LIMITS add‑on module analyzes 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.

Customer Projects of Connections

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.

Ester Tower in Jerusalem, Israel »

A wooden lookout tower called Ester, designed by the renowned Czech architect Martin Rajniš, was inaugurated in Jerusalem in mid-November 2017. The tower in the shape of a blooming cactus is located in the gardens of the former hospital, built in 1887, not far from the walls of the Old City, offering visitors a spectacular view over Jerusalem.
