Composite steel beam database for seismic design and performance assessment of composite-steel moment-resisting frame systems

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Hammad El Jisr

This paper discusses the development of a publicly available database of composite steel beam-to-column connections under cyclic loading. The database is utilized to develop recommendations for the seismic design and nonlinear performance assessment of ste ...

Concepts to minimize earthquake-induced column axial shortening in steel moment-resisting frames

Dimitrios Lignos, Hiroyuki Inamasu

Capacity-designed steel moment-resisting frames (MRFs) dissipate the seismic action through inelastic flexural yielding of protected zones located at the beam ends and the first story column bottom end. During low-probability of occurrence seismic events, ...

Enhancing Punching Strength and Deformation Capacity of Flat Slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Punching reinforcement systems have significantly developed in recent years as they allow enhancing the punching resistance of slab-column connections as well as their deformation capacity. These systems, with varying geometry and layout, normally consist ...

Experimental investigation of steel building gravity framing systems under strong earthquake shaking

Dimitrios Lignos

Hybrid simulations were conducted to evaluate the system-level seismic response of a 4-story steel moment frame building and its gravity framing system through various levels of ground motion shaking. The experimental substructure examined in detail corres ...

Response of thin lightly-reinforced concrete walls under cyclic loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

During the last two decades, thin concrete walls have been frequently used to brace mid- to high-rise buildings in some Latin American countries. This structural system differs significantly in terms of wall geometry and reinforcement layout from tradition ...

Experimental investigation of friction stresses between adjacent panels made of Oriented Strand Board (OSB) and between OSB panels and glued laminated timber (GLT) frame members

Katrin Beyer, René Steiger, Stella Nerbano

The paper presents experimental investigations of friction properties (a) between adjacent sheathing panels made of Oriented Strand Board (OSB) and (b) between OSB panels and glued laminated timber (GLT) frame members as they occur, for example, between pa ...

Improving the collapse risk of steel structures with high-performance steel

Dimitrios Lignos

With the advent of material science, high-performance steel materials have been developed for seismic applications that potentially reduce the earthquake-induced collapse risk of steel frame buildings. The High Yield Point (HYP400) steel is one of those ma ...

Influence of Lap Splices on the Deformation Capacity of RC Walls. I: Database Assembly, Recent Experimental Data, and Findings for Model Development

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini, Ovidiu Prodan

Recent postearthquake missions have shown that reinforced concrete (RC) wall buildings can experience critical damage owing to lap splices, which led to a recent surge in experimental tests of walls with such constructional details. Most of the 16 wall tes ...

Full-Scale Cyclic Testing of Deep Slender Wide-Flange Steel Beam-Columns under Unidirectional and Bidirectional Lateral Drift Demands

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

Deep and slender wide-flange steel beam-columns are commonly used in steel special moment frames (SMFs) in North America. These sections provide large moment-of-inertia required to satisfy the design code’s drift limits while keeping the column steel weigh ...

Earthquake-induced loss assessment of steel frame buildings with special moment frames designed in highly seismic regions

Dimitrios Lignos, Seong-Hoon Hwang

This paper discusses an analytical study that quantifies the expected earthquake-induced losses in typical office steel frame buildings designed with perimeter special moment frames in highly seismic regions. It is shown that for seismic events associated ...
