System variation analysis of MIG welded aluminum structural frames
… aluminum extrusions and castings welded into a structural frame. By making use of modeling techniques such as Finite Element Analysis (FEA) and Design of Experiments (DOE), it can be shown how this method can also be applied to systems that include complex processes such as welding. Modeling the …

Enhancing Progressive Collapse Resistance of Steel Building Frames Using Thin Infill Steel Panels
… installs thin steel panels into steel building structural frames to enhance the system progressive collapse resistance. </p> <p>The steel frames with simple beam-to-column connections, under different boundary conditions (i.e., sidesway uninhibited and sidesway inhibited, respectively), and the …

High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties
… technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. The criticism concerns issues as for instance short slab spans (limited flexibility …

A Fiber-Based Approach for Modeling Beam-Columns under Fire Loading
… fiber-based approach to modeling the response of structural frames subjected to realistic fire conditions. The proposed approach involves the development and validation of two finite elements that can be used collectively to simulate the thermal and mechanical response of structural frames at …

Análise por computadores digitais de estruturas reticuladas no espaço, com elemento de secção variável
… a computer program for three dimensional structural frames. The analysis is carried out with the stiffness method. Some arrangements in the stiffness matrix are made in arder to obtain a compact formulation for the problem without loss in generality. These arrangements allow the …

Modeling and Behavior of the Beam/Column Joint Region of Steel Moment Resisting Frames
… stiffness and strength of steel moment resisting frames (SMRF) has been the topic of numerous papers over the past thirty years. When properly detailed, the PZ is an excellent source of energy dissipation, even under large inelastic deformations. Due to these large inelastic deformations, the PZ …

The Science of Team Science: Exploring Principal Investigator Leadership Style and Team Collaboration Satisfaction
… members identified that the PIs used all of the frames, but were more likely to use the human resource and structural frames. The pattern of frame use resulted in the identification that PIs were more likely to adopt a multi-frame leadership style rather than the no, single, or paired styles. …

Unfolding the unexpectedness of uncertainty : arts research as a triptych installation : a conversation of processes, practices, products
… triptych, this installation involves structural frames of arts research processes, practices and products, and iconographic frames of becoming-teacher as unfolding, unexpectedness and uncertainty. I explore how arts research opens possibilities through the act and art of sharing …

Parametric analysis of progressive collapse in high-rise buildings
… The technique is applied for three different structural systems which are commonly used for high-rise buildings: moment frames, braced frames and truss tube systems. A variety of 2D structural models are analysed for their performance under progressive collapse conditions with variable …

Leadership Orientations of Female School Superintendents: A Multidimensional Framework Perspective
… Bolman and Deal's (2008) four organizational frames. A secondary purpose of this study was to create a demographic profile of female superintendents from the state of Georgia. This research was a mixed-methods study utilizing the Leadership Orientations Instrument-Self (Bolman & Deal,1990) …

Assessment of beam-to-column joint behaviour in steel-timber composite systems
Reinforced concrete slabs are among the structural components with the highest levels of embodied energy and carbon. Accordingly, replacing conventional reinforced concrete slabs with timber slab can potentially reduce the embodied energy and carbon footprint and provide opportunities for effective …

Design and Behavior of Composite Steel-Concrete Flexural Members with a Focus on Shear Connectors
… in design and construction of floor systems, structural frames, and bridges. A particularly popular system features composite trusses (joists) that can span large lengths and provide empty web space for installation of typical utility conduits. One of the prominent problems with respect to …

Organizational Factors that influence the Retention of Special Education Teachers in Osceola County
… the areas of the human resources, political and structural frames. Human resource factors included the emotional, physical, and mental toll of daily classroom responsibilities and the perceived lack of district administration support. The main structural frame factor was the lack of compensation …

Semi-rigid behaviour of plane timber structures
It is common practice in the analysis of structural frames, to either assume that the joints are pinned or rigid. In fact the real behaviour of a joint is neither pinned nor rigid, and lies somewhere between the pinned and rigid assumption. This is referred to as the semi-rigid behaviour. …

Vector-product-based Graphic Statics and Graphic Kinematics for moment-resisting structures
… focus on moment-resisting structures such as frames and beams. With the use of Vector Algebra, the main method presented here, the Gamma Superimposition Assembly method, establishes a certain design-and-analysis framework for moment-resisting structures with the definition of load paths by the …
