Ground Engineering - Essay ExamplePile foundations ar chosen for the situations where structures transmit broad adulterates and suitable grime layer capable of supporting these despatchs are available solo at greater depths. The caboodles are long and slender members capable of transmitting the loads of the structure into the hard soil layer or the rocks successfully even if very poor or cushiony soils that are considered to be inferior to meet this purpose is present in the upper layers. Based on the load carrying function muckles are classified as end pram pile, brush pile or combination pile that undertakes both the functions appropriately. The friction piles are suitable for the locations where granular soil is present and frictional resistance between the pile and the soil could be utilised in the resistance. mend the end bearing piles helps to transmit the entire load a hard stratum finished the tip resistance. A sketch of the load action on the end bearing pile a nd friction pile are shown in the figure 1. The basic structural components of any pile are pile cap and the body of the pile.And (iii) All piles carry only vertical force. ... Figure 1(a) End bearing pileFigure 1 (b) Friction pile (Abebe and Smith, 2005) (Abebe and Smith, 2005)Pile load computationFollowing assumptions are incorporated in the load estimation on piles(i)All piles are considered as unshakable (ii) The pile is pinned at the top and bottomAnd (iii) All piles carry only vertical force. The antithetical loads that the pile need to carry would be direct loads from the columns and any different obligate loads on the structure. The direct loads from the columns to the pile are already given in the problem. The other loads are the load from the glass facades and the imposed loads. The glass faade load is the load along the edges of the beautify and it could be computed by multiplying the unit load of the faade by the distance between the columns. The details of comput ation is as follows sugarcoat faade load between the columns 1 & 8Distance between the columns 1 and 8 = 20 metrewhole load of facde between the column 1 and 8 = 35 KN/mThe load from the faade is assumed to be transferred equally to both the columns . So the loads are computed as 35 20 / 2 = 350 KNSo the columns 1 and 8 would carry load of 350 KN each from the glass facades.Glass faade load between the columns 4 & 5Distance between the columns 4 and 5 = 20 metreUnit load of facde between the column 4 and 5 = 35 KN/mThe load from the faade is assumed to be transferred equally to both the columns . So the loads are computed as 35 20 / 2 = 350 KNSo the columns 4 and 5 would carry load of 350 KN each from the glass facades placed between the columns 4 and 5.Glass faade load between the columns 1 and 4The columns in this span are 1,2,3
