Study on the Mechanical Behavior of Top-Chord-Free Vierendeel-Truss Composite Slabs

Buildings
A top-chord-free Vierendeel-truss composite slab (TVCS) comprises a concrete slab, several vertical webs, and a steel bottom chord. In this study, static tests and finite element analyses were conducted based on an actual project to investigate the deformation, crack characteristics, ultimate bearing capacity, and failure mode of the composite slab ...

A New Rate‐Dependent Constitutive Model of Superelastic Shape Memory Alloys and Its Simple Application in a Special Truss Moment Frame Simulation

Advances in Civil Engineering, Volume 2018, Issue 1, 2018., 2018
In this work, a new constitutive model of the behavior of shape‐memory alloys is presented, based on earlier models, showing a very good agreement with the existing experimental results. A simple approximate application concerning the use of these alloys modelled as dissipation devices in a special truss‐moment frame is demonstrated.

Numerical analysis of the stability behaviour of castellated beams and comparison to regular hot‐rolled profiles

Steel Construction, Volume 19, Issue 1, Page 50-59, February 2026.
Abstract Castellated steel beams, characterised by their unique perforated web design, have gained significant popularity in the construction of medium‐span structures, like industrial and office buildings. These beams offer an economical solution due to their increased bending moment capacity about the major axis with relatively low weight and ...

Precast Prestressed Concrete Truss‐Girder for Roof Applications

Journal of Structures, Volume 2014, Issue 1, 2014., 2014
Steel trusses are the most popular system for supporting long‐span roofs in commercial buildings, such as warehouses and aircraft hangars. There are several advantages of steel trusses, such as lightweight, ease of handling and erection, and geometric flexibility.

Span-dependent comparative analysis of lateral torsional buckling and nonlinear load behaviour in castellated and solid I-beams using analytical and finite element approaches

Materials Research Express
Castellated beams (CB), widely employed in modern construction, offer an improved strength-to-weight ratio and enhanced structural efficiency due to their increased depth and moment of inertia.

Robustness assessment of reinforced concrete structures for different failure scenarios

Structural Concrete, Volume 27, Issue 1, Page 279-313, February 2026.
Abstract This study describes the robustness assessment of 3D reinforced concrete structures analyzing the response of the 2D frames in different design configurations and failure scenarios. The structures are characterized by both frames with wide beams and seismic‐resistant frames with deep beams.

Dynamic Response and Shear Carrying Capacity of Web‐Opening High‐Strength Steel Beams Under Impact Loads

Shock and Vibration, Volume 2025, Issue 1, 2025.
To investigate the dynamic response of web‐hexagonal‐opening high‐strength steel beams (WHOSSBs) under impact loads, drop‐hammer impact tests were conducted on 18 WHOSSBs. A numerical model was established and compared with the impact test results to verify the validity of the model.

Mechanical Performance of Reinforced Concrete Vierendeel Sandwich Plates with Upsetting Sleeve Assembled Joints Under Cyclic Loading

Buildings
In order to surmount the characteristics of high steel consumption and cost in prefabricated buildings, as a novel structural component, reinforced concrete vierendeel sandwich plates (RC-VSP) could be effectively employed. However, RC-VSP is restricted by complex construction procedures and rigorous quality control demands.
