Determination of minimum CFRP pre-stress levels for fatigue crack prevention in retrofitted metallic beams

Alain Nussbaumer, Elyas Ghafoori, Gary Scott Prinz, Andrin Herwig

The majority of fatigue strengthening studies focus on reducing propagation rates of existing cracks, ignoring the crack initiation stage. Many existing metallic bridge members however do not contain existing cracks, but rather are nearing their design fat ...

Cyclic demand at the shell-bottom connection of unanchored steel tanks

Alain Nussbaumer, Gary Scott Prinz, Gustavo Cortes

Gasoline and other oil byproducts are commonly stored in steel tanks that rest on ground without any anchorage. Under strong motion, the impulsive mass of the contained liquid generates a moment about the base of the tank capable of causing partial uplift ...

Fatigue analysis of liquid-storage tank shell-to-base connections under multi-axial loading

Alain Nussbaumer, Gary Scott Prinz

During severe seismic events the base of unanchored steel liquid-storage tanks can uplift, causing large inelastic rotation demands at the shell-to-base connections and large multi-axial stresses (radial tension and circumferential compression) in the tank ...

Dynamic performance comparison between buckling-restrained braced frames with concentric and eccentric configurations

Gary Scott Prinz

Buckling-restrained braced frames (BRBFs) are often used in steel buildings to resist seismic loads; however, BRBF ductility can be limited by poor performance of the beam-column-gusset regions. Additionally, the concentric brace configuration in BRBFs can ...

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

Alain Nussbaumer, Luís Costa Borges, Gary Scott Prinz, 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 ...

Finite element modeling for fatigue strengthening of metallic riveted bridges using un-bonded pre-stressed CFRP plates

Alain Nussbaumer, Elyas Ghafoori, Gary Scott Prinz, Andrin Herwig, Mario Fontana

Many old riveted steel bridges remain operational and require retrofit to accommodate ever increasing demands. Complicating retrofit efforts, riveted steel bridges are often considered historical structures and as such structural modifications that affect ...

Fatigue strengthening of riveted girders in a historic railway metallic bridge in Switzerland using pre-stressed un-bonded CFRP laminates

Alain Nussbaumer, Elyas Ghafoori, Masoud Motavalli, Gary Scott Prinz, Andrin Herwig, Mario Fontana

Fatigue analysis of unanchored steel liquid storage tank shell-to-base connections during earthquake induced uplift

Alain Nussbaumer, Gary Scott Prinz, Gustavo Cortes

During severe seismic events the base of unanchored steel liquid-storage tanks can uplift, causing large inelastic rotation demands at the shell-to-base connections. With repeated cycles of uplift, these shell-to-base connections are susceptible to low-cyc ...

On the low-cycle fatigue capacity of unanchored steel liquid storage tank shell-to-base connections

Alain Nussbaumer, Gary Scott Prinz

Under strong earthquake motions, the liquid stored within large unanchored steel tanks can cause rocking and uplift of the tank base from the supporting foundation. Repeated rocking can lead to low-cycle fatigue fractures in the tank base-plate, and ultima ...

Experimental and numerical investigation of ductile top-flange beam splices for improved buckling-restrained braced frame behavior

Gary Scott Prinz

Buckling-restrained braced frame performance at high drifts is improved by providing beam splices that reduce demands in the gusset regions. Existing experimental data only consider web splices without a slab present. An alternative top-flange splice, prop ...
