Substructure. American Type. Retaining wall structures prevent slopes from failing, and collapsing or moving down slope, once sections of material have been excavated from the original topography of the site. This component transfers dead loads, live loads and all other loads coming over it to the underlying soil. Foundation and basement floor cracks, wall or floor gaps, cracked chimneys, and bowed basement walls can all negatively impact the structural integrity of a home or commercial building. Foundations (footing) are then responsible of transferring all the loads to the ground or piles. Geosynthetics, known as geocomposites, are also widely available, and combine both geomembrane and geotextile materials. It is placed immediately beneath the lowest part of the superstructures. Through the baseplate, column load is transferred to the top tier. For large buildings with high loadings a deep foundation solution will be necessary to support the weight of the building and ensure limited settlement. Tap here to review the details. It appears that you have an ad-blocker running. The substructure is determined by considering the type of superstructure, construction method, ground conditions, and aesthetic factors. Generally this is low strength. In this type of foundation, the base is wider than the top to distribute the load from the superstructure over a large area. These foundations are constructed after opening the trenches to the required depth. What is Substructure and Superstructure in Building Construction?
