The summary provides high-level information on the purpose and uses of Acts as a quasi-foundation/footing system in compression – no reinforcement used Replacement of poor soil with “good soil” (concrete of a known compressive strength) Excavation is carried out and trench filled with lesser strength concrete Standard footing design then poured over this mass concrete base Cheap and quick to do so builders Stepped footing / walled foundation is used when the site has a slope, which makes drilling and burial over the foundations other than in large quantities if the designer want to make it to a single horizontal level. These types of loads are typically seismic or wind loads. Footing foundations, also known as spread, combined, or mat footings, transmit design loads into the underlying soil mass through direct contact with the soil immediately beneath the footing. g.

Footing plays a significant role 1. 0 Introduction 1. - Free download as PDF File (. Footings are designed to transmit these loads to the soil without exceeding its safe bearing capacity, to prevent excessive settlement of the structure to a tolerable limit, to minimize differential settlement, and to prevent sliding and overturning. This type of foundation is called a raft or mat foundation and may be cheaper than individual footings because of reduced forming costs and simpler excavation procedures.
