Anz_SIP-Adaptive_A4_EN--ISOcV2.indd 1 18.03.19 10:35 Dear readers,
We are the recognized market leader in the field of structural protection systems. We manufacture bridge bearings, roadway expansion joints, seismic protection devices, vibration dampers and monitoring systems. The crucial factor speaking in favor of MAURER SE: over 1,000 employees working for us worldwide.
In this magazine, you will get to know some of them, their projects, their tasks and their professional passions. In face-to-face conversations they describe what particular challenges they have to face in their daily work and how these challenges can be mastered in cooperation with customers, partners and technicians on site. Maybe you have already worked together with one or another colleague or know about projects from his/her area of responsibility. MAURER MAG has been created to provide you – in this first edition and many more to follow – with an overview of and insights into the many facets of our work.
With kind regards from Munich,
Dr. Christian Braun Max Meincke

MAURER, the tradition-steeped machinery, plant engi- neering and steel construction company from Munich looks back on a history of 140 years. Just in time for the anniversary, MAURER AG was converted into MAURER SE. The change of the legal form is a consistent step in the corporate strategy after the conversion into an incorporated company two years ago. MAURER keeps on heading towards internationalization. Managing directors of the rebranded MAURER SE are Dr. Christian Braun and Max Meincke. The company will continue Judith Klein, responsible for to be in the ownership of the Beutler and Marketing & Grill families with Jörg Beutler acting as Communication, moderates the chairman of the supervisory board. event.

GORGEOUS PARTY BY OUR OWN EFFORTS The anniversary was celebrated in cor- porate style: on the company premises at Frankfurter Ring in a production hall and a party tent, without flamboyancy but with dynamics, joy of living, and quality in detail.
Dr. Christian Braun, in a leading position with the company for more than three decades, is visibly glad about the opportunity to celebrate the anniversary with approx. 500 employees.

MAURER MAGAZINE | 19 MAURER SIP®-ADAPTIVE // NEWEST-GENERATION SLIDING ISOLATION PENDULUMS
The seismic isolator MAURER SIP®-Adaptive is a Sliding Isolation Pendulum featuring two primary sliding surfaces with an articulated slider in between. It bears the dead load of the structure and ensures re-centering of the structure through the pendulum principle. The radii and friction coefficients of the two primary sliding surfaces determine the isolation and damping of the structure. MAURER MAG talked to Hans Distl and Felix Weber, the two development engineers in charge of the product.

20 | MAURER MAGAZINE What is so special with the MAURER SIP®-Adaptive?
Hans Distl: The special feature is the considerably enhanced structural protection in case of low to middle-magnitude earthquakes, since the system has not exclusively been designed for high- magnitude earthquakes.
Felix Weber: MAURER SIP®-Adaptive acts as an isolator which effectively isolates the structure from the ground at a low excitation level. Up to now, sliding isolation pendulums have been designed for a certain operating point. In case of low-magnitude earthquakes they are not triggered at all, and in case of high-magnitude earth- quakes their performance is not really good either.
HD: Two things are required: Firstly, an effective design method is needed to determine the different properties of the MAURER SIP®-Adaptive, and secondly, the solution must be well thought-out to ensure adaptivity to the magnitude of the earthquake – this leading to the designation MAURER SIP®-Adaptive. It was a special merit of Felix that he has done lots of basic research through computer-based simulations.

MAURER MAGAZINE | 25 26 | MAURER MAGAZIN BEECKERWERTH RHINE BRIDGE // TRUST ONE IN ITS THIRTIES
How to more than double the service life of a bridge with least possible effort.
The Beeckerwerth Bridge is part of the “Emscherschnellweg” of the A 42 federal highway. It crosses the River Rhine between the Duisburg districts Beeckerwerth and Baerl. The bridge has a total length of 1,030 m, three traffic lanes in each direction and – after almost 30 years – desperately needs a thorough reconstruction.
The bridge was built between July 1986 and October 1990 with total building costs amounting to 134 million Deutschmarks. It has surely paid off, and now the exchange of the roadway expansion joints – with concurrent high traffic load – is inevitable. read more >
The two steel pylons of the cable-stayed bridge have a height of 66.7 m and are located in the center axis of the bridge. On each side, three harp-shaped cable groups are anchored in the pylons.
MAURER MAGAZIN | 27 Especially the excavation of the old roadway expansion joints was hard work.

Key part of the pilot project ”Digital Test Field Highway“. How resilient is the bridge and how long will it be fully functional?
This question comes up with each new construction and each reconstruction of a bridge. Within the scope of the project „Intelligent Bridge in the Digital Test Field Highway“ of the Federal Ministry of Transport and Digital Infrastructure (BMVI), carried out by the Federal Highway Research Institute (BASt), our engineers have created the technical basis for a more efficient and more economical maintenance management of the bridge infrastructure.
Those who want to plan and build for the future need valid data on real use. With the measuring and evaluation systems by MAURER, real-time monitoring becomes more and more feasible.
