New access road for Laue fire testing facility

New access road for Laue fire testing facility

On 5 June, North Saxony District Administrator Michael Czupalla presented Thorsten Hindemith, Chairman of the Board of the Goitzsche Stakeholder Community, with the funding decision regarding the expansion of the access road to our fire testing facility in Laue. Also present were Dr. Manfred Wilde, Mayor of Delitzsch, and Dr.-Ing. Mathias Reuschel of MFPA Leipzig.

Load frame for fire resistance testing of load-bearing wall structures

Load frame for fire resistance testing of load-bearing wall structures

In 2013, a new load frame for testing the fire resistance of load-bearing wall structures and firewalls was introduced at the fire testing facility. The load frame has a remarkably high stiffness. The wall structure to be tested is mechanically loaded from below. In the current configuration with five hydraulic presses, it is possible to apply a centric or off-centre load of 1500 kN to the test structure. In addition, the attachment surfaces for walls were extended to allow for a more convenient, unhindered attachment to the new support frame. 

Masonry walls and metal stud walls are not the only load-bearing structures for which the fire resistance is determined pursuant to DIN EN 1365-1 in conjunction with shock testing pursuant to DIN EN 1363-2 and which are classified as firewalls pursuant to DIN EN 13501-2. In recent years, load-bearing solid wood structures and timber stud structures have increasingly also been tested in the same manner. The test wall set-up personnel have access to compressed air and high-voltage current at each of the three new attachment surfaces. In addition, a second crane (10 tonne) was installed, which can traverse the entire facility. As a whole, these measures have created an environment which ensures problem-free preparation and execution of fire resistance tests, especially for manufacturers of load-bearing wall structures such as brick walls or solid wood walls.

Young scientists visit MFPA Leipzig

With their home-made frame for a fire-rated window, schoolboys Wolfgang Horn and Marvin Petau from Stolpen, Saxony, came second in the regional stage of the Jugend forscht competition for young scientists. Following their success, they wanted their design to undergo real fire testing. The frame was fitted with special glass provided by Arnold Brandschutzglas and subjected to a temperature of 1000 degrees Celsius at MFPA Leipzig’s fire testing facility in Laue. The design withstood the heat for 90 minutes, placing it squarely in the second-best fire protection category.

 

MFPA Leipzig supported the experiment as part of the Sachen Machen (Let’s Make Things) initiative led by the Association of German Engineers (VDI).

Container homes – full-scale natural fire testing

Container homes – full-scale natural fire testing

§ 14 of the Model Building Code (MBO) specifies that structural installations should be planned, constructed and maintained in such a way as to prevent the occurrence of fire and the propagation of heat and smoke (fire propagation) and to ensure that, in the event of fire, it is possible to rescue people and animals, and effectively extinguish the fire. These requirements must also be met by temporary structures such as quick-assembly container buildings.

 

The fact that individual containers are attached to a steel frame system means that it is generally necessary to verify the stability of the overall construction experimentally by means of a natural fire test on a comparable container building. 

 

The fire exposure for the test in question was selected in accordance with the guidelines set out by the building department of the city of Munich and had a fire load density (quantity of heat of all combustible materials based on the fire-cell area/fire chamber) of 800 MJ/m². 

 

CONZEPT Containerhandel GmbH produces a range of prefabricated container units. The company commissioned MFPA Leipzig GmbH to conduct fire testing on a container building in order to verify its stability and integrity over a 30-minute period in the event of a destructive fire.

 

BASt research programme on road engineering

BASt research programme on road engineering

As part of a research programme conducted by the Federal Highway Research Institute (BASt), MFPA Leipzig GmbH has been assigned the workstream “Quality assurance and repair concepts for the use of polypropylene fibre-reinforced concrete to improve the fire behaviour and spalling of the inner shell of road tunnels”. Over the next 20 months, this R&D project should answer unresolved questions relating to the use of polypropylene fibre-reinforced concrete in road tunnel construction. In the first instance, this will include analyses of the technical properties of concrete and questions related to its long-term resistance and the possibility of using polypropylene fibre-reinforced concrete to repair road tunnels on federal highways. The R&D project involves experts from the MFPA divisions Building Materials, Structural Fire Protection and Research, Development, Modelling.

Leipzig Fassadentag, 29 September 2015

Leipzig Fassadentag, 29 September 2015

On 29 September 2015, Leipzig will once again host a meeting of experts in façade construction. The trade fair city is continuing a tradition that started in 1992 with the very first symposium on façades. Façades design is at the heart of a constant change in the face of construction. With the tension between innovation and safeguarding the protective goals of the building codes, increasing importance is being placed on research on, testing and approval for façade products and their use.

Visit the Leipzig Fassadentag to find out about the latest technology – ensuring that innovations can be reliably applied. Hear from renowned scientists and experts in building inspection and practical construction on subjects including:

  • Building codes today – nationally and internationally
  • Heat protection – pros and cons of thick insulation
  • Fire protection
  • Hygrothermal performance
  • Thermal bridges and load-bearing capacity
  • The planner’s perspective

Successful seminar on sealing

Successful seminar on sealing

The 10th Leipzig Seminar on Sealing took place on 27 January 2015 in the KUBUS, Leipzig. In addition to the usual updates on standards and information about changes to building code regulations, this year the focus was on the sealing of structural installations in agriculture. Well over 100 participants from business and research heard about the latest developments from the organisers.


There is a detailed overview in German of the Leipzig Seminar on Sealing in the DIBt Newsletter 01/2015, available as a PDF download or on the DIBt website at the following link: (https://www.dibt.de/en/Service/Newsletter.html)

Experts working in the field of sealing can make a note of the next seminar in their diary now: The 11th Leipzig Seminar on Sealing will take place on 26 January 2016.
