Abstract: An exact formulation is derived for the buckling of structs supported elastically at the midspan. The formulation is based on the large deflection theory of the beam column. Two coupled nonlinear equations involving definite ...

Abstract: Previous studies on the buckling of an elastic strut with discrete flexible transverse supports indicate that a sufficient support stiffness may be found such that the flexible supports would act as rigid supports for a ...

Abstract: From experimental studies, the strength of concrete columns is known to be enhanced by lateral reinforcement. The quantitative correlation of the strength and the lateral reinforcement configuration remains difficult. In ...

Abstract: A method of determining story drift, shear, and overturning moment (OTM) from building seismic records is presented. A system‐identification technique based on modal synthesis is used first to obtain parameters of dominant ...

Abstract: Seismic records obtained during the Loma Prieta earthquake and the Whittier earthquake from 21 buildings were analyzed by a system identification method. The adequacy of current code specifications on building period ...

Abstract: A versatile beam analyzer is presented in this note. It displays shear, moment, and deflection diagrams as well as influence line diagrams of a two-dimensional beam. The computing engine of the program was carefully designed ...

Abstract: In perhaps the first nontrivial application of an alternative interfacial compatibility condition, the elasticity solution of a circular three-layer sandwich ring under two forces acting along a diameter is obtained. Within ...

Abstract: An automated damage assessment method for buildings equipped with PC-based strong-motion recording systems is proposed. The major components of the method include a postearthquake data analysis package and a multicriterion ...

Abstract: Tests on 127 × 127 × 381 mm concrete columns were carried out to study the efficacy of welded-wire fabric (WWF) as confining transverse reinforcement in columns. Three different wire spacings and a total of five wire sizes ...
