Stability Requirements of Deep Steel Wide-Flange Columns under Cyclic Loading

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

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 ...

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 ...

Updates to the ASCE-41-13 Provisions for the Nonlinear Modeling of Steel Wide-Flange Columns for Performance-based Earthquake Engineering

Dimitrios Lignos, Alexander Riley Hartloper

Performance-based earthquake engineering requires numerical models that are able to reliably predict the expected component behavior of buildings under seismic excitations. The nonlinear modeling guidelines provided in ASCE-41-13 have historically been use ...

Multi-Directional Structural Component Hybrid Testing System for the Assessment of the Seismic Response of Steel I-Shaped Columns

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Ali Imanpour

The Multi-Directional Hybrid Testing System (MDHTS) at Polytechnique Montreal is an advanced structural testing system that can be used to study the response of large-scale structural components such as columns, walls, or bridge piers subjected to any comb ...

Experimental Investigation of the Hysteretic Behavior of Wide-Flange Steel Columns under High Axial Load and Lateral Drift Demands

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper discusses the findings from a large-scale experimental program that characterized the hysteretic behavior of typical steel wide-flange columns in steel moment-resisting frames (MRFs). The test specimens were tested in a cantilever configuration ...

Simultaneous estimation of unwrapped phase and phase derivative from a closed fringe pattern

Pramod Rastogi, Rishikesh Dilip Kulkarni

We propose a new approach for the direct estimation of the unwrapped phase from a single closed fringe pattern. The fringe analysis is performed along a given row/column at a time by approximating the phase with a weighted linear combination of linearly in ...

Seismic behaviour of slab-column connections without transverse reinforcement

Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate and high seismicity. Such buildings are typically braced by RC walls, which carry the largest portion of t ...

Analytical investigation of the cyclic behavior and plastic hinge formation in deep wide-flange steel beam-columns

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper investigates the cyclic behavior of deep wide-flange sections, used as columns in steel Special Moment Frames (SMFs), through detailed finite element (FE) analysis. A wide range of wide-flange sections is subjected to symmetric cyclic lateral lo ...

Experimental testing and simulation of bolted beam-column connections having thick extended endplates and multiple bolts per row

Alain Nussbaumer, Gary Scott Prinz, Luís Costa Borges, Shyam Khadka

Retrofit of existing steel buildings often requires strengthening of the connection regions. One common connection, the bolted beam-column connection, is often strengthened in design using stiffened extended endplates, or with continuity plates welded betw ...
