Efficient Design of Sustainable Concrete Structures

At greenStruct, we are not just engineers; we are advocates of sustainable construction. Our team comprises skilled structural and software engineers driven by a commitment to designing concrete structures that are not only efficient and practical but also environmentally responsible. With expertise spanning both fiber-reinforced concrete (FRC) and conventional steel bar reinforcement, we are on a mission to impart our knowledge to the building industry and foster sustainable design practices.

greenSlab - Design Ground Supported Slabs

Effortless Slab Design with Versatile Reinforcement Option

greenSlab empowers engineers and designers to effortlessly create ground-supported slabs that meet the demands of various projects. Whether you opt for steel reinforcement, fiber reinforcement, or a combination of both, greenSlab's capabilities ensure optimal structural performance.

Key Features

  • Comprehensive Load Verification: Ensure bearing capacity against diverse loads, such as uniform, line, and point loads, on both soil/ground and insulation layers
  • Automatic Thermal Insulation and CO2 Calculations: Seamlessly incorporate thermal insulation assessments and CO2 calculations into your designs
  • Autogenerated Documentation: Simplify project management with autogenerated documentation that captures critical design details

Understanding Slabs

Slabs are foundational components that serve as both structural support and the floor of a building. They efficiently distribute loads from superstructures, like walls and columns, to a broader area of the ground or insulation. Apart from providing vertical load resistance, slabs can also contribute to stabilizing a structure by transferring horizontal forces, such as wind loads, to the ground.

Design Considerations

Designing a slab with greenSlab involves analyzing various factors, including:

  • Slab thickness, joint spacing, and field size
  • Concrete type, quality, and subbase conditions (ground/soil and insulation)
  • Anticipated loads, such as point loads, axle loads, quadruple loads, line loads, and uniform loads
  • Selection, placement, and amount of reinforcement (steel mesh, steel bars, and/or fiber reinforcement)

greenStrip - Design Strip Foundations

Optimal Strip Foundation Design for Structural Integrity

greenStrip offers engineers the tools they need to design strip foundations (wall footings) that ensure the stability and load-bearing capacity of structures. With options for steel or fiber reinforcement, greenStrip enables accurate and efficient foundation design.

Key Features

  • Comprehensive Bearing Capacity Calculation: Evaluate the bearing capacity of the concrete cross section in both transverse and longitudinal directions
  • Verification on Multiple Substrates: Verify the foundation's bearing capacity on both soil/ground and insulation layers
  • Autogenerated Documentation: Simplify project management with autogenerated documentation capturing crucial foundation design details

Understanding Strip Foundations

A strip foundation, also known as a wall footing, is a type of shallow foundation commonly employed to support load-bearing walls or closely spaced columns. By distributing loads linearly along the length of the wall or column line, strip foundations mitigate pressure on the underlying soil, thus preventing excessive settlement. They are widely used in various applications, including residential, commercial, and industrial buildings

Design Considerations

Designing a strip foundation using greenStrip involves considering various factors, such as:

  • Geometry parameters, including width, height, and wall characteristics
  • Geotechnical parameters that influence foundation performance
  • Vertical and horizontal loads imposed on the structure
  • Concrete quality and the type, placement, and quantity of reinforcement

greenPad - Design Point Foundations

Understanding Point Foundations

A point foundation, also known as a pad foundation, is a type of shallow foundation used to support individual structural elements or columns. It consists of a single, localized footing or pad that bears the load from the column and transfers it to the underlying ground/soil

Design Considerations

When making a design of a point foundation with greenPad, various considerations are analyzed:

  • Geometry

    • Length, width, and height

    • Column length and width, and column eccentricity

  • Geotechnical parameters

  • Loads

    • Vertical load

    • Horizontal loads in both directions

    • Moments in both directions

  • Concrete quality

  • Type, placement, and amount of reinforcement (steel bars/mesh and/or fiber reinforcement)

Advantages of Fiber Reinforcement for Sustainable Design

At greenStruct, we emphasize the benefits of fiber-reinforced concrete (FRC), particularly macro-synthetic polypropylene fiber reinforcement (MSFRC). Our calculations and software offer a pathway to structural strength and sustainability

Key FRC Advantages

  • Sustainability and Reduced CO2 Emissions: Polypropylene fiber reinforcement is corrosion-resistant, enabling lower exposure class and reduced cement use, leading to significantly lower CO2 emissions
  • Trusted Structural Fiber: Our choice of structural fiber, DURUS® EasyFinish from ADFIL, has undergone rigorous testing, including time-dependent durability and flexural strength assessments

Testing and Calculation

  • Notched Three-Point Bending Test: This standardized test, in accordance with EN 14651, provides crucial residual flexural strength data for FRC. This data forms the basis for calculating bearing capacity and designing concrete structures with fiber or steel reinforcement
  • From Test Results to Design: Load-deflection data from the test is converted into a stress-strain curve, enabling moment capacity calculations. This approach also accounts for shear capacity enhancement in FRC

Empowering Sustainable Design

Our software equips you to

  • Determine optimal DURUS® EasyFinish fiber and steel reinforcement dosage
  • Choose between steel reinforcement, fiber reinforcement, or a combination based on rigorous calculations
  • Use advanced calculation methods for stress and internal force analysis.
