TL;DR: In this paper, the effects of prebuckling in-plane deformations on the elastic buckling of monosymmetric arches are investigated, and nonlinear relationships between the displacements and the strains are obtained using position vectors.
Abstract: When the ratio of the minor axis flexural stiffness to the major axis flexural stiffness is not small, classical analysis may lead to an inaccurate prediction of the flexural-torsional buckling loads of an arch, because prebuckling in-plane deformations change the curvature of the arch. A systematic treatment of the effects of prebuckling in-plane deformations on the elastic buckling of monosymmetric arches is presented in this paper. Nonlinear relationships between the displacements and the strains are obtained using position vectors. Energy equations are formulated for the elastic flexural-torsional buckling of monosymmetric arches, which include the effects of prebuckling in-plane deformations, and closed-form solutions are obtained for arches in uniform bending. The effect of the arch slenderness on flexural-torsional buckling is investigated. Comparisons with the existing theoretical solutions are made.

TL;DR: In this paper, the authors proposed a simple design procedure for the placement of large web openings in reinforced concrete beams to provide effective shear reinforcement based on test evidence, and provided guidelines for placing these web openings.
Abstract: Based on test evidence, guidelines for the placement of large web openings in reinforced concrete beams are given, following which a simple design procedure is suggested Generally, openings should be positioned so that chords have sufficient concrete area to develop the ultimate compression block in flexure and adequate depth to provide effective shear reinforcement They should not be deeper than one-half the beam depth and should be located not closer than one-half the beam depth from supports or concentrated loads For analyses for elastic bending moments and shear forces by conventional methods, the recommended procedure uses an equivalent shear stiffness incorporating an effective length for the opening and considers the applied shear to be carried in proportion to the flexural stiffness of the chords The design of chords for strength follows ACI code provisions Cracking at the opening is controlled by proper detailing, while deflections are calculated using the same analysis procedure but considering cracked moment of inertia and checking against code requirements
