The lateral system in structural engineering refers to the components designed to resist lateral forces such as wind, earthquakes, and other horizontal loads that can cause significant movement or deformation in a building. In timber engineering, designing an effective lateral system is crucial for maintaining the stability and safety of the structure.
The Key Elements of a Lateral System are:
Shear Walls
Vertical elements like CLT (Cross-Laminated Timber) panels that resist lateral loads through shear forces. CLT is particularly effective in timber buildings for lateral resistance.
Braced Frames
Triangular frameworks made of timber or hybrid materials (e.g., timber-steel) that resist lateral forces through axial forces in their members.
Moment Frames
Beam-column connections that resist lateral forces by creating bending moments, often used in open-space designs.
Diaphragms
Horizontal elements like floors or roofs that transfer lateral forces to vertical elements such as shear walls or braced frames. CLT panels are commonly used as diaphragms in timber structures due to their strength and stiffness.
The Importance of the Lateral System in Timber Engineering.
Timber’s lightweight nature compared to materials like steel or concrete requires careful design of lateral systems to resist wind and seismic forces. CLT panels, braced frames, and moment frames are key components of lateral systems in timber construction, particularly in seismic regions.
When the lateral system is made of concrete or steel, the building is considered a hybrid structure rather than a pure timber structure. These hybrid systems combine the benefits of timber with the added strength of steel or concrete to optimize performance under lateral forces.
At Ergodomus, we have the expertise to properly design both the lateral system and horizontal diaphragms, ensuring they can effectively resist earthquake and wind forces. Our approach incorporates advanced analysis and detailed design to guarantee the stability and safety of timber and hybrid structures.
