Chapter 2 Loads for designing foundations

Dead loads being permanent forces action upon the structures may cause considerable settlements or dangerous shear failures. Dead loads is the weight of the structure and its permanent parts. The weight of the foundation itself and the weight of the soil on the footing are also dead loads. ...
