Design Method for the Base Beam Connected to Single Pile Cap

Abstract:

For the long elastic pile, the “m” method is often used to solve the elastic deflection differential equation, and the bending rigidity of pile can be obtained. The single pile can be replaced by one column fixed at two ends which has the same rigidity of the pile to solve the interaction problem of pile, base beam, and upper structure. So the influences of the pile construction error on base beam can be calculated. The analysis example shows that compared with no construction error of pile, the bending moment and the reinforcement of base beam increase greatly in the scope of allowable maximal construction error stipulated by the Code. The calculation method of the internal forces of base beam is put forward.
