E702.4 Designing Concrete Structures Buried Concrete Basement Wall Design (PDF)

Pdf Summary

The document titled "Designing Concrete Structures: Buried Concrete Basement Wall Design," reported by ACI Committee E702, provides guidance for designing buried concrete basement walls in single-story masonry buildings. It follows the ACI 318-19 design code and assumes specific parameters, such as a concrete compressive strength of 5000 psi and reinforcement yield strength of 60,000 psi. The design incorporates various factors like soil pressure, shear, and moment calculations, ignoring seismic influences due to the structure's location in a low-seismic area.<br /><br />The example problem outlines the determination of load, service-level shear and moment from soil pressure, and factored vertical axial forces. The document discusses designing the wall with a fixed base and pinned top, using certain assumptions to simplify calculations, such as neglecting live load buoyancy and in-plane shear. The structural design emphasizes ensuring compliance with ACI's minimum reinforcement requirements and evaluating the wall's shear and axial capacity.<br /><br />The main calculations involve determining vertical and horizontal reinforcement, while factoring in potential shear and moment strengths, wall thickness, slenderness, and stability. The provided design summary concludes that a 15-inch thick wall with specific reinforcement at prescribed spacings is sufficient for the example case.<br /><br />Furthermore, the document suggests additional considerations if the structure were in a high-seismic region or if the geotechnical report were outdated or unavailable. Additional resources for further reading include ACI 318-19 and 314-16, along with guides and textbooks on reinforced concrete design.<br /><br />This example serves as an industry-relevant case that employs common simplifications, aiming to assist designers in integrating practical and code-compliant solutions into structural designs for buried basement walls.
