Influence of Vertical Circulation Planning on Multi-Storey Building Accessibility

Abstract

The study examines the influence of vertical circulation planning on accessibility in multi-storey buildings, with emphasis on how the arrangement and design of stairs, ramps, lifts, and other vertical movement systems affect users’ ability to move efficiently and safely between different floor levels. Effective vertical circulation planning is essential in multi-storey buildings because users may have different mobility needs and varying levels of familiarity with the building. Poorly planned vertical circulation can result in difficult movement, congestion, long travel distances, restricted access, and dependence on assistance. The study will assess the relationship between vertical circulation planning and accessibility in selected multi-storey buildings. Attention will be given to the location, number, capacity, dimensions, continuity, visibility, and connectivity of stairs, lifts, and ramps, as well as their relationship with entrances, corridors, major activity spaces, and horizontal circulation routes. Accessibility will be assessed based on ease of movement between floors, travel distance, route clarity, waiting time, convenience, safety, ease of use, and the ability of different categories of users to access major building functions. A descriptive cross-sectional research design will be adopted for the study. An appropriate sample of selected multi-storey buildings and their users will be selected using a suitable sampling technique. Data will be collected through physical observation, dimensional measurements, circulation mapping, accessibility checklists, photographic documentation, and structured questionnaires administered to selected building users and relevant facility personnel. The collected data will be analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation, while appropriate comparative and correlation techniques will be applied to examine the relationship between vertical circulation planning and building accessibility. The study is expected to reveal that vertical circulation planning has a measurable influence on accessibility in multi-storey buildings. Buildings with appropriately located and adequately designed stairs, lifts, and ramps are expected to provide easier movement between floors, reduce travel difficulties, and improve accessibility for a wider range of users. Poorly positioned or inadequate vertical circulation elements may increase travel distances, create congestion, reduce route clarity, and restrict access to upper or lower floors. The effect may also vary according to building height, user volume, lift capacity, stair configuration, entrance location, and the relationship between vertical and horizontal circulation. The findings will be useful to architects, accessibility professionals, facility managers, building owners, developers, and planning authorities involved in the design and management of multi-storey buildings. The study may provide practical information for locating and organizing vertical circulation elements to improve building accessibility, movement efficiency, and user convenience. It may also support the integration of inclusive design principles into multi-storey building planning. The study will conclude by establishing the influence of vertical circulation planning on multi-storey building accessibility and emphasizing the importance of coordinated vertical movement systems in architectural design. It is recommended that stairs, lifts, and ramps be appropriately located, adequately dimensioned, clearly connected to major circulation routes, and designed to accommodate the needs of different categories of users. Further studies should examine vertical circulation planning across different multi-storey building types and levels of occupancy.
