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 ...

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 ...

Experimental Determination of the Capacity of Wall-to-Base Connections in Storage Tanks

Alain Nussbaumer, Gustavo Cortes, Eric Lattion

Earthquakes around the world have affected many unanchored tanks used for storage of gasoline. When these unanchored tanks are subjected to strong motion, the moment generated at the base, by the mass of liquid contained in the tank, will cause partial upl ...

Experimental Evaluation of Steel Slit Panel Frames for Seismic Resistance

Gustavo Cortes

The steel slit panel–frame is a new system for seismic resistance of buildings. The steel slit panels are bolted to beams which are simply connected to the columns. The steel slit panels are steel plates with rows of vertical slits forming a series of flex ...

Analysis and Design of Steel Slit Panel Frames (SSPFs) for Seismic Areas

Gustavo Cortes

The Steel Slit Panel Frame (SSPF) system is a new Seismic Force-Resisting System (SFRS) intended for areas of high seismicity. The main components in an SSPF are: steel beams and columns, and Steel Slit Panels (SSPs). SSPs are steel plates with rows of ver ...

Experimental Study on the Seismic Behavior of Shell-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

When an unanchored tank is subjected to strong motion, the impulsive mass of the contained liquid generates a moment which if strong enough could cause partial uplifting of the base plate. As the tank undergoes uplifting, the shell-base welded connection i ...

Seismic Behavior of Shell-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

Unanchored steel tanks subjected to strong ground motion may experience rocking motion if the moment generated by the inertial mass of the content stored is greater than the resisting moment provided by the weight of the tank and its content. Rocking of th ...

Seismic Behavior of Shell-to-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

A study of non-anchored tanks found in Switzerland (Koller, 2003) revealed that the plastic rotation of the shell-to-bottom connection in four of the six tanks studied did not satisfy the 0.2 radians limit established by the Eurocode (Eurocode-8, 2005). Th ...

Steel Slit Panel Frames for Lateral Resistance of Buildings

Gustavo Cortes

The Steel Slit Panel Frame system is a new promising lateral force resisting system intended for zones of high seismicity. Its main component is the Steel Slit Panel (SSP). An SSP is a steel shear wall with dimensions of roughly 5ft wide and 11.5ft tall. T ...
