Effect of Slab Stiffness on EBF Link Rotation Demands and Implications for Link Ultra Low-Cycle Fatigue Susceptibility

Albano António De Abreu E Presa De Castro E Sousa, Gary Scott Prinz

This study aims to quantify slab contributions in EBFs by investigating the dynamic performance of two 3-story EBF configurations with and without concrete slabs: one configuration having long (flexural yielding) links and the other having shorter (shear y ...

Towards displacement-based seismic design of modern unreinforced masonry structures

Katrin Beyer, Sarah Petry, Alessandro Paparo, Marco Tondelli

Unreinforced masonry (URM) structures are known to be rather vulnerable to seismic loading. Modern URM buildings with reinforced concrete (RC) slabs might, however, have an acceptable seismic performance for regions of low to moderate seismicity. In partic ...

Human convective boundary layer and its interaction with room ventilation flow

Dusan Licina

This study investigates the interaction between the human convective boundary layer (CBL) and uniform airflow with different velocity and from different directions. Human body is resembled by a thermal manikin with complex body shape and surface temperatur ...

Experimental investigation of the human convective boundary layer in a quiescent indoor environment

Dusan Licina

This study aims to characterize human convective boundary layer (CBL) in a quiescent indoor environment. The study has two objectives: first, to characterize the velocity field around the thermal manikin under two ambient temperatures and body postures; an ...

Damage predicting algorithms for regular RC structures

Pierino Lestuzzi, Amin Karbassi

In this paper a 2-phase decision tree algorithm is developed to qualitatively predict damage in RC buildings based on earthquake characteristics and structural properties. To this end, the structural properties considered are the natural period of the fund ...

Fling-step effect on the seismic behavior of high-rise RC buildings during the Christchurch earthquake

Pierino Lestuzzi, Amin Karbassi

Fling-step and forward directivity, which can impose unexpected seismic demands on structures, are the main consequences of near-fault earthquakes. Although the adverse effect of forward directivity on structures behavior is determined to some level, the i ...

Shake-table test on a four-storey structure with reinforced concrete and unreinforced masonry walls

Katrin Beyer, Sarah Petry, Marco Tondelli

With the introduction of higher seismic design forces in the Swiss loading standard of 2003 most unreinforced masonry (URM) buildings failed to satisfy the seismic design check. For this reason, in new construction projects, a number of URM walls are nowad ...

Performance-Based Seismic Vulnerability Evaluation of Masonry Buildings Using Applied Element Method in a Nonlinear Dynamic-Based Analytical Procedure

Amin Karbassi

A thorough four-step performance-based seismic evaluation for a six-story unreinforced masonry building is conducted. Incremental dynamic analysis is carried out using the applied element method to take advantage of its ability to simulate progressive coll ...

Coupled seismogenic geohazards in Alpine regions

Lyesse Laloui, Pierino Lestuzzi, Alessio Ferrari, Cyrill Silvan Baumann, Clotaire Michel, Fabrice Dupray, Amin Karbassi

COupled seismogenic GEohazards in Alpine Regions (COGEAR) is an interdisciplinary natural hazard project investigating the hazard chain induced by earthquakes. It addresses tectonic processes and the related variability of seismicity in space and time, ear ...

Development of fragility functions as a damage classification/prediction method for steel moment-resisting frames using a wavelet-based damage sensitive feature

Dimitrios Lignos

Fragility functions are commonly used in performance-based earthquake engineering for predicting the damage state of a structure subjected to an earthquake. This process often involves estimating the structural damage as a function of structural response, ...
