Analysis of the Load-Bearing Capacity of Existing Structures

Analyzing the load-bearing capacity of existing structures is essential to ensure the safety and functionality of buildings and infrastructure. This analysis evaluates how well a structure can withstand current and future loads.

Key steps include inspecting the current condition of materials, identifying any damage or degradation, and comparing the original design criteria to current loading requirements. For building repurposing or increased load demands, such as additional floors or heavier installations, a load-bearing capacity analysis is crucial.

This analysis allows engineers to optimize structural performance, identify necessary reinforcements, and comply with safety standards. It contributes to more sustainable management and extends the lifespan of the structure.

Advisory Services for Building Repurposing

Repurposing buildings is a sustainable and creative solution to give existing structures a new lease on life. This process involves adapting a building for a different function than it was originally designed for. Examples include transforming old factories into lofts, churches into libraries, or office buildings into residential complexes. Repurposing helps preserve cultural heritage, reduces construction waste, and minimizes the ecological footprint compared to demolition and new construction.

A thorough structural analysis is essential when repurposing a building. Every structure is designed with specific functions and loads in mind, and a new use may introduce different demands on the load-bearing structure.

Strengthening with Bonded Reinforcement

Strengthening concrete elements is a widely used technique to improve the load capacity, stability, and durability of existing structures. This may be necessary when dealing with increased loads, altered functional requirements, or damage caused by aging, overloading, or external factors.

An effective method involves the use of bonded reinforcement, such as carbon fiber-reinforced polymer (CFRP) strips. These strips are adhered to concrete surfaces using specialized adhesives, providing additional strength without significantly increasing weight or volume. Other techniques include applying external steel plates or injecting cracks with reinforcing resins.

By strengthening concrete elements, the lifespan of a structure can be extended, safety requirements can be met, and repurposing or more intensive use can be achieved without the need for full replacement.

Fire Resistance Calculation at the Element Level

The fire resistance of a structural element determines how long it can withstand the effects of fire, such as high temperatures, without losing its load-bearing or separating function. At the element level, this is calculated to meet regulations and ensure the safety of the entire structure.

Relevant factors include material properties, element dimensions, loading, and thermal exposure. For concrete, this involves analyzing reinforcement cover, concrete composition, and material temperature sensitivity. For steel elements, protective measures such as fire-resistant coatings are crucial to delay critical temperatures.

Calculations help implement targeted measures, such as increasing cover, applying protective layers, or selecting fire-resistant materials. This enhances the safety of buildings and protects occupants in case of fire.

Conducting Load Tests

Load tests are practical assessments used to verify the load-bearing capacity and performance of an existing structure under realistic load conditions. This method is commonly applied to bridges, floors, or other load-bearing elements to validate calculations or assess the current condition of the structure.

During a load test, a controlled load is applied, and deformations and stresses are precisely measured. The results provide insight into structural performance and potential weaknesses, such as aging, damage, or hidden flaws.

Load tests are a valuable tool to ensure safety, assess reinforcement needs, and establish a solid foundation for renovation or repurposing projects.
