چکیده
In the design and assessment of precast concrete beams with a slab cast on top, namely composite beams, engineers still face in practice unsolved shear-related issues, such as contribution to shear strength slab, be considered formulations or influence interface between concretes behaviour. present research, 69 tests were performed monolithic rectangular T-shaped cross-section, without transverse reinforcement different qualities, experimentally analyse issues mentioned above. The study transfer mechanisms at failure led formulating model for explaining observed results. Based this model, predictive formulation web has been developed, which verified experimental results from research 24 additional literature. This provides accurate predictions compared current codes EC2, MC-10 ACI 318-19. proposed lays foundations future development user-friendly calculating beams.

A reinforced concrete member in which the total span or shear span is especially small in relation to its depth is called a deep beam. In this study, a new approach based on the Adaptive Neural Fuzzy Inference System (ANFIS) is used to predict the shear strength of reinforced concrete (RC) deep beams. A constitutive relationship was obtained correlating the ultimate load with seven mechanical a...

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
