An investigation on the seismic behavior of castellated beams under explosion loads effect

Environment Conservation Journal, 2015
Due to the widespread use of ceilings with T-shaped beams as well as because of economic problems and the lack of sufficient variation of rolled profiles, applying castellated beams in buildings with steel structure has become quite common.

Effect of column base strength on steel portal frames in fire [PDF]

, 2012
In the UK, the design of steel portal frame buildings in fire is based on the Steel Construction Institute (SCI) design method, in which fire protection needs only be provided to the columns, provided that the column bases are designed to resist an ...

Open strings in Lie groups and associative products [PDF]

, 2006
Firstly, we generalize a semi-classical limit of open strings on D-branes in group manifolds. The limit gives rise to rigid open strings, whose dynamics can efficiently be described in terms of a matrix algebra.

Calculation method of stability bearing capacity of transmission tower angle steel considering semi-rigid constraint

Curved and Layered Structures, 2022
The angle steel member is the most commonly used component form of the transmission tower structure. Considering its connection characteristics, we must deal with its stability analysis under semi-rigid constraint conditions for the proper study of the ...

A review of progressive collapse research and regulations [PDF]

, 2014
History has demonstrated that buildings designed to conventional design codes can lack the robustness necessary to withstand localised damage, partial or even complete collapse. This variable performance has led governmental organisations to seek ways of

Rigidity of Spreadings and Fields of Definition [PDF]

, 2017
Varieties without deformations are defined over a number field. Several old and new examples of this phenomenon are discussed such as Bely\u \i\ curves and Shimura varieties. Rigidity is related to maximal Higgs fields which come from variations of Hodge

Semi-rigid behaviour of stainless steel beam-to-column bolted connections

Sustainable Structures, 2021
Stainless steel is increasingly used in structural applications but there is still significant lack of experimental evidence on the moment-rotation (M-) behaviour of moment resisting beam-to-column connections.
