Truss Tuesday: Floored Question: While the TPI Technical Advisory Committee recommends that the minimum grade of visually stress-related lumber used for truss chords should be No. 2 grade, could you hypothetically use No. 3 for either one and still perform under capacity? Top and Bottom Chords are Southern Pine No. 2 Webs are Southern Pine No. 3 Building Code: IBC 2021 Loads (psf unless otherwise noted): TC Live Load 40 TC Dead Load 10 BC Live Load 0 BC Dead Load 5 The answer will be posted on Thursday! This is not a production truss! This is simply an example for Truss Tuesday conversation.

Truss Tuesday Time! Question: Will this truss work? An additional 20psf uniform dead load has been added to B1 between W3 and W4 to accommodate storage (not for lifting that engine out of your project car). The top and bottom chords are Southern Pine No. 2 and the webs are Southern Pine No. 3. Loads: TC Live Load 20 TC Dead Load 10 BC Live Load 0 BC Dead Load 10 Additional Uniform Dead Load: 20psf on B1 Application: Residential This is not a production truss! This is simply an example for Truss Tuesday conversation. The answer will be posted on Thursday! #trusstuesday #truss #trusses #woodconstruction #structuralengineering #engineering #trussdesign

Quantity material takeoffs and estimates for lumber scope of work include but are not limited to linear footage of floor or roof joints, counts of LVL beams, counts of headers, square footage of wall farmings and square footage of floor and roof sheathings. #UrbanPlanning #SustainableBuilding #TransportationEngineering #GeotechnicalEngineering #WaterResourcesEngineering

Understanding the grade of lumber is crucial for ensuring the success of your construction project. Grades vary depending on factors like strength, appearance, and suitability for different applications. Always consult with your local hardware store to determine which grade best suits your project's needs. Construction grade lumber is typically a reliable choice for most projects, offering durability and strength. However, for specialized projects requiring higher structural integrity, structural grade lumber may be necessary. Knowledge is key when it comes to selecting the right lumber for your project. Our knowledgeable and friendly staff are here to assist you every step of the way, ensuring you find the perfect materials to bring your vision to life.

A discontinuity of the insulation and reality. A few people suggested a summary page of my paper looking at the real-world performance (and consequences) of light steel framing and its (un)suitability for use as a direct swap for timber framing - as the NCC and NatHERS currently treats this material.

Metal building roof systems, while improved over the years, often face challenges with purlin strength, especially when retrofitting older structures. In the article by Tim Lane and Cris Moen, Ph.D., PE, we explore how historical designs may not meet modern standards, leading to potential overstress in purlins. The analysis of a 1989 metal building in Ohio shows significant strength deficits when evaluated with current codes. The article emphasizes the need for accurate engineering assessments to address these issues and explores effective retrofit solutions, including additional purlin lines and external reinforcements. This underscores the importance of aligning existing structures with contemporary performance standards. 📖Read the article: https://lnkd.in/gMKa5P9Q #StructuralEngineering #MetalBuildings #RetrofitSolutions

🏗️ Why Aluminum Coils Are the Top Choice for Construction 🔧 Aluminum coils offer durability, corrosion resistance, and lightweight properties that make them essential for building projects. Whether for roofing, cladding, or structural applications, learn how aluminum coils can enhance the performance and longevity of your construction projects. #ConstructionMaterials #AluminumIndustry #InquivixTechnologies #BuildingInnovation

🦺❗️LETS TALK ABOUT THERMAL EXPANSION CO-EFFICIENTS OF DIFFERENT BUILDING MATERIALS AND HOW THEY AFFECT OR CAUSES CRACKS BETWEEN RCC & MASONRY! Just about every type of material used in construction is affected by expansion to some degree. It’s so important for engineers to understand how different materials will respond to temperature change for design purposes. Cracks appearing on the joints between RCC and Masonry is due to different properties of materials, qualities, different expansion and contraction coefficients as well as young modulus being different, therefore expecting them to be homogeneous (or completely unified) after joining them at a junction will not be possible ………. WHAT DO YOU THINK?

Surveyors frequently see cavity trays being used at the DPC level between the external masonry cladding and timber frames. As reasonable as it might seem to stop water from getting in, it can actually hurt drainage and ventilation. Read about it on our technical blog here: https://bit.ly/3z8kCAt
