Evaluation of Code Accidental-Torsion Provisions Using Earthquake Records from Buildings
Building code provisions for accidental torsion are evaluated from analysis of earthquake-induced motions of three nominally-symmetric-plan buildings. The results demonstrate that the...

Improved Torsional Analysis Procedure for Single Story Structures Subjected to Seismic Motion
An analytical procedure is developed that enables designers utilizing the UBC planar lateral force procedure to accurately account for the additional lateral response due to torsion without...

Evaluation of US Seismic Code Provisions for Asymmetric-Plan Systems
The effects of plan asymmetry on the earthquake response of code-designed, one-story systems are identified with the objective of evaluating how well these effects are represented by torsional...

Thin-Walled Finite Element for Curved Multicell Box Girders
The generalized Vlasov's thin-walled beam theory was combined with the finite element technique to develop a new curved thin-walled multicell box girder finite element which can model...

Orthotropic Rigidities of Curved Concrete Waffle Slabs
Analytical expressions are derived for predicting the flexural and torsional rigidities during the pre-cracking and post-cracking stages for horizontally- curved waffle slab structures....

Prediction of Wind-Induced Responses and Wind Loads
The Recommendations for Wind Loads of Buildings and Structures of the Architectural Institute of Japan have now been updated. This paper presents the drafts of the new Recommendations...

Stresses in Open Section Fiber Reinforced Composite Beams Under Constant Shear Loading
A strength of materials approach from the ply level is used to derive expressions for stresses in statically determinate open section composite beams subjected to constant shear loading....

Bidirectional Seismic Response of Simple Structures
For design purposes it has been common to consider that seismic excitations act in one direction at a time. Analytical studies over the past decade have indicated that this may not be...

Liquefaction Flow Failure of Silty Sand by Torsional Cyclic Tests
The use of undrained strain-controlled cyclic torsional loading of anisotropically consolidated triaxial specimens (CyT-CAU tests), is proposed for evaluating liquefaction flow failure...

Torsional Simple Shear Apparatus for Drained and Undrained Cyclic Testing
Since a cyclic triaxial compression apparatus was first used to study liquefaction of saturated sandy soil, many different types of cyclic shear devices have been used to investigate drained...
