In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...

the current building codes provide limited prescriptive guidance on design for protection of buildings due to progressive collapse. progressive collapse is a situation in which a localized failure in a structure, caused by an abnormal load, such as explosions or other happenings. three procedures, often employed for determination of the structural response during progressive collapse i.e. linea...

effect of small al additions, from 0.14% to 0.31% ai, on the hot deformation behavior of low carbon steels containing 1%cu-1.2%mn was investigated in the temperature range of 750-800•c over the strain rate range of 1o.3.1o.1s•1 by a hot compression testing machine. the flow curves obtained, exhibited typical characteristics of dynamic recovery type of softening mechanism, and the critical strai...

The concept of a “dynamic frame” is introduced for use in the analysis of event structure. It is the external boundary metaphorically encircling a perceived event which determines the temporal scale on which the event is interpreted. The dynamic frame is used in two examples to simplify the analysis of English phenomena: 1) it is shown that semelfactive verbs can be considered a special case of...

The flexible nature of immunoglobulins is clearly demonstrated in electron micrographs of antibody complexes, and serves as the structural basis for the interpretation of time-resolved fluorescence depolarization studies. The extent of the flexibility seen with the electron microscope (EM) will be the initial topic of this review. We will compare rabbit polyclonal and mouse monoclonal antibodie...

Social creatures interact in diverse ways: forming groups, mating, sending emails, and sharing ideas. Some of the interactions are accidental while others are a consequence of the underlying explicit or implicit social structures [5, 6, 22, 28]. One of the most important questions in sociology is the identification of such structures, which are variously viewed as communities [8, 9, 11,12,24,36...
