Additive Manufacturing (AM) is a well-known and rapidly advancing method, especially in the manufacturing of high-strength lightweight microstructures. Utilizing AM, it possible to fabricate any structure as complicated is. For an efficient cost-effective printing, critical parameter infill, which can be characterized from easy 2D shape high complexity. At same time, Topology Optimization (TO) ...

The aim of this study is to compare the seismic performances strengthening techniques applied reinforced concrete (RC) non-ductile frames tested under effects loads. In experimental part study, one-third scale, one-bay, two-storey hollow brick infilled RC were strengthened with five different and reversed cyclic lateral One being reference, bricks plastered on both sides, one was plain mortar, ...

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 (USPSW) experimentally numerically. As result, two specimens 1:3 scale three-story single-bay IWS-SPSW USPSW were fabri...

Maars are monogenic volcanic edifices of peculiar morphology with a wide circular crater surrounded by a low gentle rim of erupted pyroclastic material. Craters of maars are deeply incised into underlying rocks (frequently down to the aquifer), which explains their frequent partial or complete water infill. Owing to their morphological peculiarities, maars are easily identifiable in air photos.

The paper introduces a new approach to kriging based multi-objective optimization by utilizing a local probability of improvement as the infill sampling criterion and the nearest neighbor check to ensure diversification and uniform distribution of Pareto fronts. The proposed method is computationally fast and linearly scalable to higher dimensions.

The present study is concerned with the simultaneous optimization of the size of components and the arrangement of connections for performance-based seismic design of low-rise SPSWs. Design variables include the size of beams and columns, the thickness of the infill panels, the type of each beam-to-column connection and the type of each infill-to-boundary frame connection. The objective functio...

Red brick is one of the materials that still quite widely used in construction practice, because it easy to get and price relatively cheap. masonry wall a pair consisting binder (mortar) filler (red brick) known as masonry. Masonry generally provides durable construction, where constituent material, mortar quality, workmanship greatly affect durability overall construction. The installation inf...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...
