The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

Structural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Design Method for Local Buckling Resistance of Double Steel Plate–Concrete Composite Walls with Stiffening Ribs and Tie Plates

Buildings
An ordinary double steel plate–concrete composite wall (ODSC wall) is composed of core concrete, the faceplates, and shear connectors such as studs, etc. Based on an ODSC wall, a new type of stiffened double steel plate–concrete composite wall (SDSC wall)

Moment‐curvature behavior of continuous reinforced concrete slab strips—Experimental determination and modeling

Structural Concrete, EarlyView.
Abstract With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...

Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Free vibrations of the infinite plate strengthened by the stiffening ribs.

Mechanics - Proceedings of National Academy of Sciences of Armenia, 2011
The natural vibrations of the infinite rectangular plate, strengthened by the periodically located transverse identical stiffening ribs, prepared of another more durable material are investigated. The optimum geometric parameters of construction are determined, which ensure the greatest value of the lowest frequency of the natural vibrations, with its ...

Material-Constructive Features and Structural Behavior of Sicilian Thin Shell Vaults

Buildings
Thin-tile vaults, characterized by a wide variety of geometric configurations, represent an important part of the architectural heritage in Southern Italy. Many of these structures are still in serviceable condition.

Methodological Challenges in Studying Wealthy Families

The British Journal of Sociology, EarlyView.
ABSTRACT Studying the wealthy is not easy. This piece provides suggestions for recruitment, interview strategies, and design to gain high‐quality data on wealthy people. It is based on an interview study of 81 US racially‐diverse families with a median net worth of $25 million. First, to gain access to the wealthy, it is key for the researcher to use a
