This document summarizes the load calculations for a beam. It lists the permanent loads from a lightweight concrete slab as 350 kg/m2 for the slab, 100 kg/m2 for brick finishes, and 20 kg/m2 for ceilings, totaling 470 kg/m2. It then calculates the permanent load on the beam as 1739 kg/m from the slab load over 3.7 meters. Additional permanent loads on the beam include its own self-weight of 360 kg/m and 30 kg/m from brickwork, totaling 390 kg/m. The total permanent load on the beam is calculated as 2129 kg/m.

CARGAS PERMANENTES DEL ALIGERADO:
PESO DE LOSA ALIGERADA = 350 Kg /m2
ACABADO DE LADRILLO = 100 Kg /m2
CIELORRASO = 20 Kg /m2
470 Kg /m2
WCP = 470 Kg /m2 X 3.70 m = 1739 Kg /m
CARGA DIRECTA DE LA VIGA:
PESO PROPIO DE LA VIGA = 0.50 m X 0.30 m X 2400 Kg/m3
= 360 Kg /m
LADRILLO PASTELERO EN L A VIGA = 100 Kg /m2 X 0.30 m = 30 Kg /m
= 390 Kg /m
PESO TOTAL DE LA CARGA PERMANENTE EN LA VIGA:
WCP = 2129 Kg /m S/C = 400 Kg /m
