Non-negligible sectional deformations, such as warping and distortion, occur in thin-walled
beams under a twisting moment. For accurate analysis, these deformations need to be …

Steel sections have several applications in the construction industry. They are often used in
the design and construction of huge industrial complexes. They also are used in transport …

Many engineering structures consist of thin-walled beams and shells. Especially for fast
design in an early design stage, a simplified analysis using beams for load-carrying …

In higher-order beam theories, cross-sectional deformations causing complex responses of
thin-walled beams are considered as additional degrees of freedom. To fully capture their …

Higher-order sectional modes of a thin-walled beam such as distortion and warping
significantly affect structural stiffness levels. Because this higher-order effect becomes even …

This study presents a new modeling technique to estimate the stiffness matrix of a thin-
walled beam-joint structure using deep learning. When thin-walled beams meet at joints …

A new systematic approach is presented to derive the cross-section deformation modes of
thin-walled beams with arbitrary sections within the framework of a higher-order beam …

This paper presents a one-dimensional finite element analysis of tapered thin-walled box
beams under out-of-plane loads and twisting moments by developing new C 0-continuous …

A new joint modeling method for a beam-based analysis of a car body applied during the
concept design phase is presented. The body-in-white (BIW) of a car mainly consists of thin …

Thin-walled multicell structures observed in vehicle frames are partially welded to lower the
welding process cost while maintaining their overall structural stiffness comparable to those …
