Analysis and computer program for non-prismatic continuous beam and floor section
… were developed for theoretically analyzing continuous non-prismatic T-beams. Residential floor systems were treated as a series of three-span continuous T-beams. Cross-sectional area of the stem of the T-beam was doubled over interior supports and for 3 ft. on either side. Computer programs …

Exploring the Mechanical Behavior of a Traditional Japanese Joint for Flexible Structural Design
… Element Analysis (FEA), the study examines a continuous beam and an unmodified MRO splice, revealing expected behavior in the beam and unexpected tress concentration and displacement asymmetry in the splice. Topology optimization of the splice’s end sections yields iterations with varying …

Investigation of the behavior of continuous beams under steady state forced vibration
… the problem of steady-state forced vibration of continuous frames. Starting with the analysis of a single span, simply supported beam, the method was extended to continuous beams and frames. An investigation of his method was undertaken comparing experimental deflection with those predicted by …

Shear strengthening of pre-cracked and non pre cracked reinforced concrete continuous beams using bi directional CFRP strips
Shear failure of a reinforced concrete beam is catastrophic where it occurs suddenly and without any warning. The use of FRP sheet as a strengthening and repairing material is an effective method to enhance the shear capacity of the beam. Extensive researches have been conducted on the shear …

A performance analysis of the hi-plan structural apparatus
… such objectives, two structural models (a continuous beam and a portal frame) were extensively tested under several loading and support configurations. The models were analysed using STRUDL as well as a computer program developed by the author. The comparison of the results (deformations) …

Evaluation of software for analysis and design of reinforced concrete structures
… structures were considered including a four span continuous beam, a two story 3-D frame, a seven story 3-D frame, and a fourteen story 3-D frame. The study compared the accuracy of the programs as well as their functionality. In the evaluation of the accuracy of analysis results, factors such as …
