International Journal of Concrete Structures and Materials, 2022 In the construction of concrete bridges, the lighter dead load of decks can significantly reduce the number or size of substructure members, such as girders, piers and foundations. Although, the arch decks (ADs) ensure superior load carrying capacity and

Behavior of composite pre-flat slabs in resisting punching shear forces
Alexandria Engineering Journal, 2020 Due to large use of the composite pre-flat slabs “two layers slabs” especially manifested in pre-cast system slabs such as frequently used in bridge dicks, large thickness slabs casted on two layers or change usage of existing structure.

Investigation of longitudinal reinforcement contribution in shear punching of reinforced concrete flat slabs without transverse reinforcement [PDF]
MATEC Web of Conferences, 2019 The shear punching of the reinforced concrete slabs is a complex process occurring when considerable force is concentrated on the relatively small area of a column-slab connection. An incorrect assessment of load capacity of slab under the punching shear

Post punching shear pattern and progressive collapse of flat slab building [PDF]
Revista IBRACON de Estruturas e Materiais, 2023 The possibility of the occurrence of a second punching shear failure and of a Progressive Collapse after a punching shear failure had occurred in one flat slab column connection is investigated in two building structures, using Eberick and SAP2000 ...

A review of progressive collapse research and regulations [PDF]
, 2014 History has demonstrated that buildings designed to conventional design codes can lack the robustness necessary to withstand localised damage, partial or even complete collapse. This variable performance has led governmental organisations to seek ways of

Effect of premature loading on punching resistance of reinforced concrete flat slabs
Case Studies in Construction Materials, 2020 Premature loading of reinforced concrete flat slabs in multi storey buildings during construction may occur after shuttering removal and loading slabs earlier than usual to meet project time targets.

Facta Universitatis. Series: Architecture and Civil Engineering, 2021 The paper first presents the calculation of the punching shear capacity of concentrically loaded reinforced concrete column footings according to the current Eurocode 2, which can be carried out in two ways: by conducting an iterative procedure and by a ...

The hybrid of floating stone column by numerical and physical evaluation [PDF]
, 2018 Rapid population growth amplifying demand for accommodation and infrastructure has resulted in soft ground being increasingly used in construction. Problems related to soft ground can be remedied by adopting a ground improvement technique.

Reduced area approach for predicting punching shear resistance of biaxial hollow slabs with openings
Results in Engineering, 2023 Due to the inclusion of hollow plastic spheres in bubbled slab systems, the shear resistance is greatly reduced. Also, the existence of the opening in the vicinity of columns takes away part of the concrete responsible for resisting shear forces and ...

Numerical investigation of the punching shear resistance capacity of reinforced concrete slab
IOP Conference Series: Materials Science and Engineering, 2023 Abstract The article studies the punching shear capacity of reinforced concrete slabs by simulation method. Based on the Concrete Damage Plasticity (CDP) constitute model, the simulation model is established in the Abaqus software. The simulation model was verified by the comparison of punching shear tests.
