NBC 105: Seismic Design of Buildings

NBC 105: Seismic Design of Buildings is a PDF regulatory document providing mandatory structural criteria for seismic safety in Nepal. This document serves as the official 1994 edition of the Nepal National Building Code 105, specifically addressing seismic design requirements for building construction. It functions as a technical manual for engineers and architects to ensure structural integrity against earthquake loads. The content includes defined seismic zones, design methodologies, and performance criteria necessary for compliance within the region. As a legal instrument issued by the Department of Urban Development and Building Construction, it outlines the essential parameters for structural analysis, material specifications, and detailing practices required to mitigate seismic risks in new and existing building projects.

Professionals integrate this PDF document into their structural design workflow as a primary reference for compliance and calculation validation. Engineers typically use the code to determine lateral force requirements, site-specific seismic coefficients, and structural system limitations during the preliminary design phase. By cross-referencing the technical clauses with project-specific structural models, practitioners ensure that their designs meet mandatory national safety standards. The document remains a critical resource for drafting structural reports and preparing permit documentation for development projects across Nepal.
