One of the most instrumental aspects governing the response of structural concrete at ultimate limit state refers to the possibility of developing smeared cracking patterns within a member (associated normally to the presence of sufficient reinforcement fo ...
In materials, the evolution of crack surfaces is intimately linked with the self-contact occurring between them. The developed contact forces not only mitigate the effect of stress concentration at crack tip but also contribute sig- nificantly to the trans ...
In steel moment resisting frames (MRFs) with composite floor slabs, seismic loads are transmitted from the slab into the beam through shear studs. Shear strength degradation of the studs due to cyclic loading results into the loss of the load transfer mech ...
Residual stresses are investigated for the first time in a dissimilar AA1050-DP450 steel magnetic pulse weld using neutron diffraction. Close to the joint interface, tensile residual stresses are observed in the Al sheet and compressive residual stresses a ...
This paper estimates the impact of stress-testing on lending spreads. We use firm-level data on syndicated loans matched with bank holding company (BHC) data in our panel regressions. Using a difference-in-difference framework, we find: (1) BHCs that faile ...
We present a computational framework for modeling and optimizing complex assemblies using cone joints. Cone joints are integral joints that generalize traditional single-direction joints such as mortise and tenon joints to support a general cone of directi ...
In materials, the evolution of crack surfaces is intimately linked with the self-contact occuring between them. The developed contact forces not only mitigate the effect of stress concentration at crack tip but also contribute significantly to the transfer ...
This work investigates the fatigue resistance of reinforced Ultra High Performance Fiber Reinforced Cementitious composite (R-UHPFRC) beams with special consideration of steel rebar – UHPFRC interaction under tensile stresses due to bending. Experimental t ...
The loading path the fault experiences is often neglected when evaluating its potential for reactivation and the related seismic risk. However, stress history affects fault zone compaction and dilation, and thus its mechanics. Therefore, in incohesive faul ...
In Switzerland, the peak period for the construction of large hydropower plants dates back than 50 years ago. Only in the '80s a reaction was discovered, which generates internal swelling of the concrete and causes permanent damage to the structures. The r ...
