Background to the Model Code 2010 Shear Provisions - Part II Punching Shear
نویسنده
چکیده
This paper outlines the theoretical background of the punching shear provisions implemented in the fib Model Code 2010 and presents a practical example of its application. It is the aim to explain the mechanical model that forms the basis of the punching design equations, to justify the relevance of the provisions and to show their suitability for the design and assessment of structures. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

Punching strength of actual two-way slabs
Many building codes rely on empirical formulations with respect to the punching shear design provisions. Such empirical equations are typically calibrated on the basis of laboratory tests performed on simplified geometries (usually isolated specimens) with usually statically-determined loading conditions. On the contrary, actual structures, particularly two-way slabs, are continuous and highly ...
متن کاملEstimation of Punching Shear Capacity of Concrete Slabs Using Data Mining Techniques
Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...
متن کاملImproving the Punching Shear Strength of RC Slabs by FRP and Steel Sheets
This paper deals with the modeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The FE numerical models are validated by comparing with the experimental results obtained from tested specimens and...
متن کاملEvaluation of the SEAOC/UBC97 Provisions for the Tall Base-Isolated Structures
The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...
