Performance Based Analysis of Shear Wall with Flexible Soil Base

Shear wall is usually modeled with different types of elements with fixed base to tolerate lateral load. Membrane, plate and shell elements are chosen to model shear wall without reinforcement. In the present study an attempt is made on a 3D, 10 storey building with flexible soil base. The building is analyzed with and without shear wall. The shear wall is provided at all four corners throughout the height of the building. The building is resting on flexible soil base and analyzed for nonlinear analysis. The shear wall is modeled with different elements and different number of layer section (i.e., concrete and steel layers). Shear wall is modeled separately with membrane, plate and shell elements. In addition to this combination of elements is also tried to model shear wall. The combination to model shear wall chosen is plate and membrane element with variation in number of concrete and steel layers. This study is helpful to predict response of shear wall provided with various elements. It gives us idea as to model shear wall with elements separately or in combination. The behavior of shear wall modeled with variation in concrete and steel layers is also predicted.

Efficient Visualization Method of Buckling Region in Dynamic Transient Analysis of Cable Network Structures

Deployable structure system using flexible members is necessary to construct a large structure in the space. The flexible members easily buckle as seen in wrinkles and slack. Therefore, it is available at designing of spacecraft to grasp when, where and how large the buckling occurs in the entire structure during the deployment. When dynamic analysis of large flexible structures which can ignore bending is conducted, the truss element and the membrane element, which do not consider the bending of an element, are often used from the viewpoint of calculation cost. Therefore, this paper proposes a comprehensive and efficient visualization method of buckling occurrence region and buckling magnitude during dynamic response analysis using the truss element to progress convenience in design. The method proposed in this paper is based on two previous studies. The proposed method is verified by a simple truss model, and an application example is shown.
