Biomass Boiler House in Kočevje, Slovenia
Customer Project
Due to new technological demands, the investor Melamin d.d. Kočevje decided to replace the old steam boiler using fossil fuel (Đuro Đakovič, No. 5356) with a new one with total power of 9.8 MW.

Model
The new system for steam production consists of biomass storage, a transport and delivery system for woodchips, a steam boiler, and an ash collector.
The new boiler house was a demanding project from a technological and execution point of view. The construction was also difficult because it took place while the existing boiler (Loos, No. 61428) was in operation. The old boiler is currently used for temporary steam production, while in the future, it will only be used as a backup.
Structure
The structure of the main building of the boiler house is made of steel and enclosed with metal facade panels. The main building is 74 ft long, 41.8 ft wide and 49.4 ft high. There are two extensions connected to the main building of the boiler house.
The length of the first one is 49.4 ft and its width is 15 ft. The length of the second one is 74 ft and its width is 15.4 ft. The main building has another extension with dimensions of 67.3 ft x 8.5 ft, used for a conveyor belt for biomass. This building is also covered with metal facade panels and serves as a connection between the main building and the woodchip storage.
The biomass storage facility is made of reinforced concrete. It is 109.12 ft long and 35.1 ft wide. Next to the biomass storage facility there is also a liquid fuel storage area for the existing boiler (Loos, No. 61428), a command room, and an electrical room.
The interior of the boiler house contains a load-bearing steel structure used for the installation of technological equipment for the new boiler.

The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
- How can I efficiently define line hinges on several surfaces?
- How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?

How do I include the overstrength factor(s), Ωo in the ASCE 7 load combinations?
- My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations?
