Ramps as Performative Infrastructures: Obliqueness, Embodiment, and the Governance of Access

Within regulatory documents, technical manuals, and compliance-led architectural practice, ramps are predominantly described through measurable requirements such as gradient, width, landings, handrails, and surface characteristics. While these criteria establish essential minimum conditions of access, they may also encourage designers and approving authorities to treat the ramp as a compensatory addition to an already defined spatial arrangement. This paper does not attribute this instrumental understanding to disabled people or disability advocates; rather, it identifies a recurrent tendency within professional practice to separate accessibility from architectural conception. Drawing upon Claude Parent's fonction oblique, Le Corbusier's promenade architecturale, accessibility research, Disability Studies, and the theoretical contributions of Judith Butler and Bruno Latour, the paper interprets the ramp as a performative infrastructure: a spatial device that generates architectural form, organises embodied movement, and shapes participation. The study adopts a critical interpretative methodology combining architectural theory, the social model of disability, the International Classification of Functioning, Disability and Health, Universal Design principles, and evidence-based accessibility standards. Selected projects are examined as architectural demonstrations rather than as models of regulatory compliance. The analysis distinguishes three interconnected but non-equivalent conditions: spatial generativity, measurable accessibility performance, and equitable participation. The paper argues that a ramp becomes an instrument of Universal Design only when architectural continuity is combined with equitable use, low physical effort, legibility, appropriate gradients, resting opportunities, and integration within the principal circulation system.
