CLT AND MASS TIMBER - Load-Bearing Wall Construction System - Horizontal Loads

Sep 15, 2026

CLT AND MASS TIMBER presents design and build solutions for solid wood panel systems, focusing on load-bearing wall construction and the need to manage horizontal actions from wind and earthquakes. The document explains how floor-level loads create shear and tension forces that must be absorbed through correctly designed connection systems to prevent failure modes. It outlines standard and innovative approaches for brackets, plates, concealed and distributed joints, uplift and ground connections, and supporting profiles that improve durability, performance, and versatility.

CLT AND MASS TIMBER Solutions to design and build with solid wood panel systems CLT AND MASS TIMBER LOAD-BEARING WALL CONSTRUCTION SYSTEM HORIZONTAL LOADS During the design phase of a building its reaction to horizontal and vertical actions such as, wind and/or earthquakes must be considered. Horizontal actions can be schematised as loads acting on the floor levels. To guarantee the adequate seismic performance of timber buildings and avoid all the possible failure modes, it is fundamental to design all the connection systems correctly. LOAD PATTERN STANDARD APPROACH INNOVATIVE APPROACHES tension angle-brackets shear angle-bracket shear and tensile angle bracket constructive angle bracket universal angular bracket Horizontal loads acting at the floor level introduce shear and tension forces on the structural elements of the building; these forces must be absorbed by an effective connection system. A complete range of joints for walls and buildings also allows for innovative design approaches.

FAQs

Why must horizontal and vertical actions be considered during building design?

During the design phase, the building’s reaction to horizontal and vertical actions such as wind and/or earthquakes must be considered. This ensures adequate seismic performance and helps avoid failure modes.

How do horizontal loads at floor levels affect timber building elements?

Horizontal loads acting at floor level introduce shear and tension forces on the building’s structural elements. These forces must be absorbed by an effective connection system.

What types of CLT and mass timber connections are highlighted?

The document highlights connections such as angle brackets, two-dimensional plates, concealed joints, distributed joints, special connectors, and self-drilling screws. Each category supports tensile and/or shear transfer depending on the selected model.
