The tangent stiffness method provides a useful and simple algorithm to find shapes of curved surfaces, which can be applied to membrane and cable net structures. This paper proposes a control technique of loading and displacing, when the method is applied to shape analyses under inner pressure. The proposed technique, named “Simultaneous control”, can find high-rise and large volume shapes, which are in the state over the maximum point of its p-v pass. The technique controls both of compulsory displacements on a control point and the inner pressure derived from the shape in each iteration step at the same time. As a result, when the unbalanced forces on every node converge as well as the average of converted inner pressure, the rational form is found.
