Abstract The interaction between cladding panels and the main structure is a crucial point to assess the seismic response, and above all the structural safety, of RC precast industrial building. In the past, connections were often designed to allow construction tolerances and to accommodate both thermal and wind-induced displacements. The lack of specific details to allow relative in-plane displacements between cladding panels and the main structure often led to the participation of cladding panels in the structure seismic-resistant system with consequent connection failures.

The strong earthquakes occurred in Southern Europe in the last decade pointed out a poor seismic performance of the connection system of the cladding of precast industrial structures. The cladding of these buildings usually consists of sandwich concrete panels of remarkable mass, connected to the frame structure with mechanical devices. The estimation of the out-of-plane seismic action on these connections is a key step for their correct proportioning. However, the formulation currently provided in the Eurocode 8 for the estimation of the seismic action on non-structural elements was calibrate

This paper develops a novel dry connection utilizing high-strength bolts and introduces the corresponding low-rise precast wall panel structure system. To investigate the seismic performance of the structure system with full bolt connections, monotonic loading tests of the connection joint and cyclic lateral loading tests of three full-scaled precast shear walls are both conducted. Based on the test data, axial and shear mechanical models of the connection are given. Meanwhile, experimental results show that the failure mode of the connection is dominated by anchored rebar ductile rupture, and

To explore the performance of the flexible nodes between the precast concrete wall panel and the frame structure, a steel truss is used as an analogue of the frame structure to develop a test. In the test, one precast concrete wall panel was installed on the steel truss, and the connection nodes are designed to be able to slip vertically. Different horizontal forces were exerted on the steel truss to form certain drifts, and the deformation of panel and the slipping performance of the connection nodes were explored.

Summary. As cities develop, there is a rising trend towards the construction of multi-storey buildings. The main reason is dense urban development and rising land prices. One of the most common materials for the construction of multi-storey buildings is monolithic reinforced concrete. Monolithic structures allow architects to freely design the interior space, as well as more evenly distribute the forces in the frame elements, and the building works as one rigid structure. At the same time, the construction of monolithic structures requires significant time for construction and highly qualified

In this case a space-harmonic-based approach is used, and first-order shear deformation theory is employed to account for the wavefield's in-plane/out-of-plane coupling effect in the skin. The panel's stiffeners interact with the skin through internal forces and moments at the connections.

In the seismic design of steel moment-resisting frames (MRFs), the panel zone region can significantly affect overall ductility and energy-dissipation capacity. This study investigates the influence of panel zone flexibility on the seismic response of steel MRFs by comparing two modeling approaches: one with a detailed panel zone representation and the other considering fixed beam-column connections. A total of 30 2D steel MRFs (15 frames incorporating panel zone modeling and 15 frames without panel zone modeling) are subjected to nonlinear time–history analyses using four suites of ground mot

Steel plate shear walls (SPSWs) offer good energy dissipation capability when subjected to seismic forces as a robust lateral load resisting structure. This research investigated the cyclic behaviors of innovative infill web-strips (IWS-SPSW) and conventional unstiffened steel plate shear (USPSW) experimentally and numerically. As a result, two specimens of a 1:3 scale three-story single-bay IWS-SPSW and USPSW were fabricated and tested under cyclic lateral loading. Rigid moment-resistant connections were used for the steel plate shear wall beam-column connection. The steel shear walls with in

Introduction. The stiffness of prefabricated disks and diaphragms is considered a key parameter in designing multi-story buildings with wooden frames. Under the action of horizontal wind and seismic loads, the stiffness of wooden structures and their connections affects the distribution of forces among the structural elements and floors of the building. The stiffness and ductility of the joints in disks and diaphragms determine the dynamic characteristics of the building frame, such as the structural logarithmic decrement and damping ratio. The stiffness of vertical and horizontal joints influ

Within the EU’s environmental policy, redevelopment strategies must be designed by adopting an integrated approach. This approach considers energy savings in buildings and seismic safety as driving forces of economic growth. The recent technological evolution experienced by the construction sector has aimed to define a new building element, the seismic coat. This term refers to a structural “skin” that improves both the seismic safety and the energy efficiency of existing buildings according to standards identified by current regulations.

Drawing on data from 77 non-financial firms listed on the Amman Stock Exchange between 2015 and 2023, the study evaluates the impact of five core board characteristics: board size, board ownership, political connections, board independence, and gender diversity on dividend policy. A panel data regression model was employed to assess these relationships. The analysis revealed statistically significant positive effects of these governance features on dividend payout ratios.

Beam–column connections are the most critical components of reinforced concrete (RC) structures. They serve as a load transfer path and take a significant portion of the overall shear. Joints in RC structures constructed with no seismic provisions have an insufficient capacity and ductility under lateral loading and can cause the progressive failure of the entire structure. The joint may fail in the shear prior to the connecting beam and column elements. Therefore, several modeling techniques have been devised in the past to capture the non-linear response of such joints. Modeling techniques u

Single-sided formwork supporting systems (SFSSs) play a crucial role in the urban construction of retaining walls using cast-in-place concrete. By supporting the formwork from one side, an SFSS can minimize its spatial footprint, enabling its closer placement to boundary lines without compromising structural integrity. However, existing SFSS designs struggle to achieve a balance between mechanical performance and lightweight construction. To address these limitations, an innovative instrumented SFSS was proposed.
