Abstract

Abstract

The reinforced concrete segment is an important supporting component in tunnels and subway stations， and its mechanical properties determine the engineering quality of these structures. Currently， traditional reinforced concrete segments are designed with large dimensions， requiring substantial amounts of concrete and posing transportation challenges. To address these issues， this paper proposes embedding hollow steel pipes within traditional reinforced concrete segments， innovatively introducing a composite structural segment combining hollow steel pipes and concrete. This study conducted eccentric compression performance tests on three full-scale segment specimens and thoroughly analyzed their failure modes， failure mechanisms， bearing capacity， and crack development under eccentric loading. Based on experimental research， a calculation method for the bearing capacity of composite structural segments under eccentric loading was derived and established. The research results showed that the bonding performance between hollow steel pipes and concrete in composite structural segments was good， and the two materials could work together effectively. The composite structural segments exhibited good bearing capacity and stiffness. The lateral deflection of specimen ZHGP-2 was the smallest at both yield and peak stages， showing a 36% reduction compared to specimen ZHGP-1 and a 24% reduction compared to specimen ZHGP-3； the load of specimen ZHGP-2 reached its maximum at both yield and peak stages， with the peak load increasing by 6% compared to ZHGP-1 and by 15% compared to ZHGP-3. This indicated that the prestressed specimen ZHGP-2 significantly improved its crack resistance， bearing capacity， and stiffness. Finally， a formula for calculating the ultimate bearing capacity of eccentrically compressed sections in composite structural segments was established. The experimental results agreed well with theoretical calculations， demonstrating significant performance advantages and broad application prospects in subway station segment design.
