Theoretical and experimental short-term behavior of non-symmetrical wall pile retaining systems

摘要

Optimized non-symmetrically reinforced piles for retaining walls constitute a new structural element recently used in constructions such as the underground floors of San Antoni Market in Barcelona or in the Riyadh metro. Piles usually have circular cross sections with longitudinal reinforcement composed of bars of the same diameter and with constant clear distances between them. The use of non-symmetrical piles in retaining walls means savings of up to 50% in the weight of the longitudinal reinforcement, compared with traditional symmetrical piles.
