ECP-201_ Ch.4 Live Load on Roofs and Examples _Lecture 2.pdf
0 likes78 views
The document outlines the Egyptian Code for Loads (ECP-201) concerning various load considerations on buildings and bridges, including dead loads, live loads, wind loads, and seismic loads. It includes detailed calculations for live loads on different types of roofs based on various conditions and slope factors. The content is organized into chapters, addressing specific loads and structural considerations for both buildings and bridges.

Live load on Roof Example(1): Calculate Live load for inclined roof has a slope 1:10 in the following different cases : A) Accessible concrete roof (Rigid) B) Inaccessible concrete roof (Rigid) C) Inaccessible corrugated sheet roof (Flexible) Solution:- Case (A):Accessible concrete roof (Rigid) 𝐿𝐿 = 200 − (200−50) 0.6 𝑥 tan 𝛼= 200 − 200−50 0.6 𝑥0.1 = 175𝑘𝑔/𝑚2 Case (B):Inaccessible concrete roof (Rigid) 𝐿𝐿 = 100 − (100−50) 0.6 𝑥 tan 𝛼= 100 − 100−50 0.6 𝑥0.1 = 91.7𝑘𝑔/𝑚2 Case (C):Inaccessible corrugated sheet roof (Flexible) 𝐿𝐿 = 60 − (60−20) 0.6 𝑥 tan 𝛼= 60 − 60−20 0.6 𝑥0.1 = 53.33𝑘𝑔/𝑚2 LL (kg/m’) 1 10
