ㅣConditions of Designㅣ
1.Elastomeric Bearing Pads are designed based on factors as followingsExpansion and Contraction of Beam △ 1 15m/m Dead Loads WD 35Ton Live loadsWL 20Ton Total Loads ∑ W=WD + WL 55TonHorizontal Seismic Coefficient KH 11 0.2 Width of Beam b 450m/m ≒ 400m/m
2. If actual Beam is 450mm wide, providing that it is made of concrete and cuts off theboth edge as 25mm, then calculating : 450mm – (25mm x 2)=400mm
