The new Chapter 9 of Eurocode 8 Part 3 for Seismic Assessment of Existing Steel Structures

Dimitrios Lignos

The seismic assessment of existing steel structures necessitates the development of practice- oriented engineering models for use in nonlinear static and dynamic analysis procedures. These models should encompass the full range of the anticipated nonlinear ...

Seismic performance of steel columns interacting with embedded column bases while exhibiting inelastic deformations

Dimitrios Lignos, Hiroyuki Inamasu

Observations from past earthquakes indicate that embedded column bases (ECBs) in steel moment resisting frames (MRFs) exhibited inelastic deformations while they were designed to be non-dissipative. Consequently, the amount of inelastic damage concentrated ...

Seismic design of non-dissipative embedded column base connections

Dimitrios Lignos, Hiroyuki Inamasu

Embedded Column Base (ECB) connections in seismically resistant steel moment frames are commonly designed to be stronger than the connected column, to protect them from inelastic actions. This relies on estimation of demands induced by the column and the s ...

Effect of Column Base Flexibility on the Hysteretic Response of Wide Flange Steel Columns

Dimitrios Lignos, Hiroyuki Inamasu

Recent experiments on wide flange steel columns subjected to multi-axial cyclic loading underscore the influence of the member end boundary conditions on strength and stiffness deterioration due to coupling of local and lateral torsional buckling. Field ob ...

Comparison of Seismic Design Requirements for Steel Moment Resisting Frames with Emphasis on Stability of Columns in North America, New Zealand, and Europe

Dimitrios Lignos

The seismic design provisions and stability requirements for steel columns used at the first storey of MRFs as specified is Canadian steel design standard (CSA S16), U.S. design provisions for steel buildings (AISC 341 and AISC 360), the New Zealand steel ...

Development of a displacement-based design approach for modern mixed RC-URM wall structures

Katrin Beyer, Alessandro Paparo

The recent re-assessment of the seismic hazard in Europe led for many regions of low to moderate seismicity to an increase in the seismic demand. As a consequence, several modern unreinforced masonry (URM) buildings, constructed with reinforced concrete (R ...

Fragility Analysis of Existing Unreinforced Masonry Buildings through a Numerical-based Methodology

Pierino Lestuzzi, Amin Karbassi

As an approach to the problem of seismic vulnerability evaluation of existing buildings using the predicted vulnerability method, numerical models can be applied to define fragility curves of typical buildings which represent building classes. These curves ...

The levels-of-approximation approach in MC 2010: application to punching shear provisions

Aurelio Muttoni, Miguel Fernández Ruiz

In order to address how new knowledge influences design expressions, design codes have in most cases become significantly more complex over the last decades. However, this tendency is leading to codes that are too complicated for preliminary design but sti ...

New analytical fragility curves for existing URM buildings in regions with moderate seismicity

Pierino Lestuzzi, Marcelo Rafael Oropeza Ancieta

Seismic risk in regions with moderate seismicity, such as Switzerland, was largely underestimated. A vast majority of existing buildings have been built without specific earthquake resistant features and do not meet modern requirements. Although several pr ...
