Reinforced Concrete Beam Rebar Detail Section for Building Grade 1

Detailed structural engineering drawing showing reinforced concrete beam sections and longitudinal reinforcement details for a Grade 1 building project. This drawing features cross-sectional views (Corte Sección Viga) at key grid locations with square beam profiles measuring approximately 30cm x 30cm. Longitudinal beam sections (Corte Longitudinal) are shown along axes A, B, and C with various vertical positions (N+2.50, N+5.30, N+7.75). Each beam contains primary tensile reinforcement and stirrup configurations (estribos) with typical spacing patterns. The document includes a typical stirrup distribution diagram (Esquema típico distribución de estribos en vigas) showing proper placement at critical zones. Reinforcement details indicate #3 and #4 rebar with standard hook configurations at beam ends. The drawing employs a 1:20 scale for section details and 1:100 scale for longitudinal views, with all dimensions specified in millimeters according to standard structural concrete practices.
