📄 Abstract（原文）
The construction industry accounts for a substantial share of global greenhouse gas emissions, largely driven by cement manufacturing. Reducing cement consumption through strategic material substitution is therefore central to achieving more sustainable construction outcomes. One viable pathway involves identifying lightly stressed regions within structural members and replacing the conventional concrete in those zones with lower‐embodied‐energy alternatives, such as brick masonry or recycled aggregates, thereby cutting both material consumption and associated carbon output. This paper examines infilled RC beams as a structurally sound and environmentally responsible alternative to conventional beam design. In a standard RC beam, the tensile zone near the neutral axis carries relatively low stress; substituting this region with brick units reduces structural self‐weight and lowers material cost without undermining load‐carrying capacity. The extent of the substitutable zone is established through the stress‐block framework of IS: 456‐2000, applied in conjunction with the mechanical properties of the replacement material. Because the resulting member acts as a multilayer composite, a rigorous analytical tool is essential. The present work employs the method of initial functions (MIFs), an elasticity‐based approach that avoids kinematic assumptions, to determine stress and displacement fields throughout the composite cross‐section under service loading. The primary contributions of this study are threefold: (i) the sustainability‐oriented concept of replacing low‐stress concrete with bricks to reduce cement consumption and carbon emissions; (ii) the specific application of the MIFs to infilled RC beams as a three‐layer composite system; and (iii) a quantitative assessment of stress and displacement distributions across five different replacement ratios (20%–80% and 100%). The present study extends the framework to systematically evaluate the effect of varying replacement ratios on structural performance, neutral axis migration, and composite action, providing new design‐relevant data not previously available.
