Abstract
Folded plate structures such as roofs and curtain walls are flexible structures, and supported by flexible supports. The behavior of such structures under dynamic and static loads, especially earthquake loads, is affected by their flexible supports and joints.
In the first part of this thesis, a new finite element model based on theories used in SAP2000 program is presented, this model is extended to include flexible joints between plates. Results from this model agree well with experimental and theoretical work done by earlier investigator.
In the second part of this thesis, the above model was used to study the behavior of glass curtain wall structures. In these structures, a special member was introduced to act as ”a spring” with nonlinear properties to transfer loads to the ground. The degrees of freedom of this member were defined. The behavior of real glass curtain wall structure was studied. The static ans dynamic response of this structure were introduced. The internal forces and stresses for this structure were calculated and studied. Design recommendations were also introduced.
In the third part of this thesis, concrete folded plate structures supported by flexible supports are studied. In this part, differences types of flexible connections are presented, and the effect of using flexible supports is studied.
