Earthquake-induced collapse risk assessment of steel frame buildings requires the use of simulation models that can realistically replicate dynamic instability of frame buildings. Such models for steel columns should consider the coupling between the axial ...
The skin is not only the largest human organ, capable of accomplishing distributed and multimodal sensing functions. Replicating the versatility of skin artificially is a significant challenge, not only in terms of signal processing but also in mechanics. ...
Just recently, valuable experimental data that characterized the hysteretic behavior of deep wide-flange steel columns (i.e., column depth, d >16 inches) at full-scale became available. Such members are typically used in steel moment-resisting frames (MRFs ...
Additive manufacturing is becoming one of the key methods for reproducing repair sections in remanufacturing processes. The major advantage of using additive processes is to minimize production time and waste. However, the surface quality and shape accurac ...
Two applications of post-tensioned CFRP strap elements recently developed at the Composite Construction Laboratory (CCLab) of the Swiss Federal Institute of Technology Lausanne (EPFL) are presented. The first application concerns post-tensioned non-laminat ...
The design of reinforced concrete flat slabs in practice can be governed at failure by punching shear close to concentrated loads or columns. Punching shear resistance formulations provided by codes are calibrated on the basis of experimental tests on isol ...
Adding a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over a Reinforced Concrete (RC) slab is an efficient reinforcement method for existing structures. The thin layer of UHPFRC serves ...
Reinforced concrete slabs with uniform thickness are common in residential and commercial buildings but can also be found in other types of structures. Such slabs are susceptible to punching shear failures, where a supporting column penetrates through the ...
Provisions for punching shear design of reinforced concrete slabs are usually calibrated on the basis of results from tests on isolated specimens that simulate the slab zone within the points of contraflexure around a column. However, the punching behavior ...
