Postsupported

Postsupported refers to a structural design approach where a horizontal element, such as a beam, slab, or bridge deck, is supported by vertical posts or columns. These posts transfer the load from the horizontal element down to the foundation or underlying structure. This method is common in various construction applications, including bridges, elevated walkways, and certain types of building construction where an open space is required beneath the supported surface.

The design of postsupported structures requires careful consideration of the loads the posts will bear, their spacing, and the materials used for both the posts and the supported element. The stability of the entire system relies on the integrity of the posts and their connections. Common materials for posts include concrete, steel, and timber. The arrangement and number of posts are determined by the span of the horizontal element and the anticipated weight it will carry. In some cases, bracing may be incorporated between posts to enhance lateral stability, especially in areas prone to wind or seismic activity. This system allows for significant flexibility in architectural design, enabling the creation of open, column-free spaces at ground level or the elevation of structures above ground.
