Structural analysis & product development

LPS (Light Protection Screen) is a modular climbing protection-screen system for high-rise buildings. Its development included type calculations for the overall system, structural verification of individual components, FE analysis for component optimisation and laboratory component tests, including tests on the climbing shoe.

Verification was carried out to DIN EN 12812, DIN EN 12811-1 to -3, DIN EN 1993-1-1, DIN EN 1993-1-5, DIN EN 1993-1-8 and DIN EN 1995-1-1. Wind-tunnel studies were coordinated for the grid elements to determine project-specific pressure coefficients for cases not covered by DIN EN 1991-1-4.

Work completed by Dr.-Ing. Alexander Enders while employed by PERI GmbH & Co. KG as a structural engineer in technical R&D (2014–2017).

A new top rail and knee rail were developed for PERI UP Flex so the leading-edge guardrail could be installed safely from the protected level below.

The installed-state verification followed DIN EN 12811-1:2004-03. Design was carried out to Eurocode 3 using FE-supported evaluation in accordance with EN 1993-1-14.

Drop tests to GS-PS-15 validated the verification concept. All requirements were met and the calculations were incorporated into approval Z-8.22-863. Work completed by Dr.-Ing. Vahid Pourostad while employed by PERI SE as Product Structural Engineer.

The LPS climbing shoe, connecting the climbing rail to the structure, and the SCS angle adapter, used to fit climbing units to inclined concrete surfaces, were investigated numerically and experimentally.

The work included FE stress and deformation analysis under governing ultimate and serviceability states and laboratory tests to validate the calculation models.

The iterative coordination of simulation and testing ensured load-bearing capacity, serviceability and reliable system function and enabled structural optimisation. Work completed by Dr.-Ing. Alexander Enders while employed by PERI GmbH & Co. KG in technical R&D (2014–2017).
