<\/p>\nTypes of Footing in Building Construction Footing:<\/b>\u00a0 The\u00a0 function\u00a0 of a footing\u00a0 or a foundation\u00a0 is to transmit\u00a0 the\u00a0 load form\u00a0 the structure\u00a0 to the\u00a0 underlying\u00a0 soil.<\/p>\n
The\u00a0 choice\u00a0 of suitable\u00a0 type of\u00a0 footing\u00a0 depends on the\u00a0 depth\u00a0 at which\u00a0 the\u00a0 bearing\u00a0 strata lies,\u00a0 the\u00a0 soil\u00a0 condition\u00a0 and\u00a0 the type\u00a0 of superstructure.<\/p>\n
Following\u00a0 are the\u00a0 different\u00a0 types\u00a0 of footing\u00a0 used\u00a0 for concrete\u00a0 structure<\/p>\n
1.\u00a0 Isolated\u00a0 footing<\/p>\n
2.\u00a0 Combined\u00a0 footings<\/p>\n
3.\u00a0 Strap footing<\/p>\n
4.\u00a0 Mat or raft\u00a0 foundation<\/p>\n
5.\u00a0 Pile\u00a0 foundation<\/p>\n
<\/p>\n
Isolated\u00a0 footings<\/b>\u00a0 are provided\u00a0 under\u00a0 each column\u00a0 and may\u00a0 be square,\u00a0 rectangular,\u00a0 or circular\u00a0 in\u00a0 plan.\u00a0 Footing\u00a0 may\u00a0 be flat\u00a0 or tapered.<\/p>\n
<\/p>\n
Combined\u00a0 footings<\/b>\u00a0 are provided\u00a0 to support\u00a0 two or more\u00a0 column\u00a0 loads.\u00a0 These\u00a0 may\u00a0 be continuous\u00a0 with\u00a0 rectangular\u00a0 or trapezoidal\u00a0 in\u00a0 plan\u00a0 as shown.\u00a0 Combined\u00a0 footings\u00a0 become necessary\u00a0 under\u00a0 the following\u00a0 circumstances:<\/p>\n
