| Summary |
Pneumatic membrane structures are usually assembled before the inflation. Then the air is blown into the inner space to give tensions tress to their thin surface skinsEwhich keeps the air pressure inside. Before this inflation process numerical simulation is usually required because the membrane and cable reinforcements experience large shape transformation during the inflation. HoweverEbecause of indeterminacy of the solving processEconventional load -control analysis can not be performed properly. Especially when the inner pressure balances with the dead load this problem is very crucial. In the Inflation process air-molecular-weight increases certainly. In the paperEfor pneumatic membrane structuresEnew analytical procedure with mole-control is proposed. AndEnumerical analysis for inextensional displacement using isoparametric membrane elements is reported.
