Deformation capacity evaluation for flat slab seismic design

Aurelio Muttoni, Lorenzo Martinelli, António Manuel Pinho Ramos, Andri Setiawan

In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of the slab around the column (punching failure) is typically the governing failure mode which limits the deformation capacity and can potentially lead to ...

Combined Shear-Flexural Verification Of In Plane Loaded Reinforced And Unreinforced Masonry Walls

Lorenzo Benedetti

The safety verification of in-plane loaded masonry panels requires the evaluation of at least three different collapse conditions connected with overturning, shear sliding, and shear - compression failure at the panels' toe. In reinforced panels, the resis ...

Static behavior of reinforced UHPFRC beams with minimal cover thickness

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

Because of its high tensile strength and deformation capacity, UHPFRC (Ultra High Performance Fiber Reinforced Cementitious composite) can theoretically be used without any reinforcement bars or prestressing. However, for more economical design and for rea ...
