Steel plate shear walls (SPSW) have been used as the primary lateral force resisting system in buildings. Extensive analytical studies on steel plate shear walls in the United States, Canada, Taiwan and other countries have already validated the simple analytical model known as strip model to predict the monotonic behavior of this kind of structural system. However, more research is still neede...

To improve the durability and serviceability of reinforced concrete structures, different variants dual-phase reinforcing steel were developed within research project NEWREBAR. The investigated variant new material, termed DPD2 steel, has a specific microstructure that increases corrosion resistance, but its yielding strength is less than Tempcore B500B. no plateau, which characteristic convent...

As global interest in using engineered wood products in tall buildings intensifies due to the “green” credential of wood, it is expected that more tall wood buildings will be designed and constructed in the coming years. This, however, brings new challenges to the designers. One of the major challenges is how to design lateral load-resisting systems (LLRSs) with sufficient stiffness, strength, ...

Abstract: Polyurethane-steel sandwich structure, which creatively uses the polyurethane-steel sandwich composite as a structural material, is proposed to strengthen the impact resistance of buildings under debris flow. The impact resistance of polyurethane-steel sandwich structure under debris flow is investigated by a series of impact loading tests, compared with that of traditional steel fram...

The improvement and the capacity assessment of existing buildings has become the main topic of the last years so that different studies can be found devoted to damaged structures or structures not having a capacity compatible with the safety levels of the actual codes. Reinforced concrete framed structure buildings represent a conspicuous rate of the existing constructions so many efforts are a...

Abstract—Past earthquakes have shown that seismic events may incur large economic losses in buildings. FEMA P-58 provides engineers a practical tool for the performance seismic assessment of buildings. In this study, FEMA P-58 is applied to two typical Italian pre-1970 reinforced concrete frame buildings, characterized by plain rebars as steel reinforcement and masonry infills and partitions. G...

This paper presents results of a study on distributed, or parallel, evolutionary computation in the topological design of steel structural systems in tall buildings. It describes results of extensive experimental research on various parallel evolutionary architectures applied to a complex structural design problem. The experiments were conducted using Inventor 2003, a networkbased evolutionary ...

Abstract Apart from the general state of the tendon the quantity of the stress in the prestressed steel is of prime importance for the safety assessment of prestressed structures and/or anchor systems. On account of precaution reasons it was necessary to create a reliable, sturdy and competitive measuring device for the direct stress monitoring in prestressing steel elements being used in sensi...

The authors propose a design philosophy for steel buildings in moderate seismic regions that draws on familiar concepts of ductility and capacity design, but also integrates the concepts of reserve capacity, elastic flexibility and strength to broaden the field of design possibilities. The paper discusses structural systems representing each of these concepts: Moderate-Ductility Concentrically-...

One of the main tasks of engineers is to design structural systems light and economic as possible, yet resistant enough to withstand all possible loads arising during their service life and to absorb the induced seismic energy in a controlled and predictable fashion. The traditional trial-and-error design approach is not capable to determine an economical design satisfying also the code require...
