We study the effect of a dimplelike geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite element modeling, and numerical solutions of a reduced sh ...
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 ...
The safety of buildings which have been affected by a natural disaster such as an earthquake is currently evaluated manually by certified inspectors who identify visible damage on the structural elements. This process has been proven to be time-consuming, ...
Concrete-filled steel tube (CFT) columns offer significant advantages over columns made of either steel or concrete alone, such as large energy dissipation and increased strength and stiffness. To further improve the seismic performance of these columns, a ...
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 ...
Single plate shear tab connections are a simple means to connect beams to their supporting members. The tab is fillet-welded to the supporting column in the fabrication shop, and then field bolted to the beam web on the construction site. Sit-uations may a ...

Extended shear tab connections have been widely used to connect simply supported beams to the flange or web of supporting columns, as well as the web of steel girders. The American Institute of Steel Construction (AISC) introduced the use of extended shear ...
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 ...
This paper discusses the findings of an experimental program that was conducted to investigate the behaviour of extended shear tab beam-to-column and beam-to-girder connections that are commonly used in North America. The laboratory results showed that ext ...
Provisions for punching shear design of reinforced concrete slabs are usually calibrated on the basis of results from tests on isolated specimens that simulate the slab zone within the points of contraflexure around a column. However, the punching behavior ...
