Updating code conforming wood designs

Designing large buildings with wood offers distinct design options typically not found in other structural materials, along with advantages in economics, energy efficiency, and other sustainability factors. However, building codes and standards are often perceived as too complex for designers and builders, so many provisions that allow for wood...

Using shear transfer at engineered wood floors

Engineered wood products are specified for a wide range of light-frame floor assemblies in light commercial and multi-family construction. I-joists, glued-laminated timber (glulam), rim board, laminated veneer lumber (LVL), laminated strand lumber (LSL), and oriented strand lumber (OSL) are popular due to their availability, precision, strength, and consistent quality.

Solid timber, solid construction performance

Solid timber construction, sometimes called ‘mass timber,’ is an emerging set of engineered wood products—massive planar or frame elements used for walls, floors, roofs, partitions, and core elements of a building. As shown in Figure 1, examples include both glued configurations liked glued-laminated timber (glulam), structural composite lumber (SCL),...

Using modern wood for historic restoration

When it comes to historic preservation projects, architects and installers can find themselves at a loss. Wood is the most traditional material, but also notoriously unstable. It has a tendency to warp and becomes vulnerable to rot, decay, and insects. Some replacement products are more durable, but far from...

Designing All-wood Podiums

Wood ‘podium’ construction takes an age-old material and moves it into the 21st century. Structures retain sought-after features—beauty, familiarity, and carbon sequestration—while soaring to greater heights and achieving sometimes dramatic cost savings.

Addressing Skilled Labor Shortages with SIPs

by Joe Pasma, PE The good news is commercial construction is picking up after several dismal years, with construction spending projected to be 5.5 percent higher in 2014 than 2013. The bad news is the Associated General Contractors of America (AGC) has pointed out “a skilled labor shortage in the...

Energy Efficiency and Building with Wood

The combination of wood and energy efficiency in construction can be the result of new wood technologies. Introducing new sustainable forestry management policies and manufacturing with engineered lumber products will lead to alternative building practices using glued-laminated (glulam) and cross-laminated timber (CLT), computer-aided manufacturing, and optimal value-engineered framing. The...

Design of Fire-resistive Exposed Wood Members

The article offers an in-depth look at design considerations for fire resistance when building with wood products. It also looks at wood engineering mechanics and design procedures that comply with the International Building Code (IBC), recognizing fire resistance demonstrated by structural wood beams and columns in actual fires.
