In European seismic areas timber structures are found as building frames, in combination with masonry infills, in bridges, but most frequently in roof structures and floor slabs of traditional buildings. Seismic strengthening of existing structures should provide a well-defined and simple path to seismic forces, maintain timber members elastic, and develop as much as possible the post-elastic b...

The construction of reliable numerical models is a key aspect within the seismic assessment existing unreinforced masonry buildings. However, it also complex process due to many uncertainties involved that can affect structural response. In situ tests allow for acquisition data at local scale. Nonetheless, supplementary information representing global response necessary overcome other (i.e., wa...

The present article seek to investigate the function of elliptical steel damper function in steel frames seismic resisting. The elliptical damper is a kind of earthquake energy dissipater in structure which acts based on the steel yielding feature. Thus, this damper in frame lateral displacement mechanism is expected to have a satisfying hysteretic behavior in terms of energy absorption is on a...

Walls and frames have different deflection lines and, depending on the seismic mass they support, may often possess different natural periods. In many cases, wall–frame structures present an advantageous behavior. In these structures, the walls and the frames are rigidly connected. Nevertheless, if the walls and the frames were not rigidly connected, an opportunity for an efficient passive cont...

ABSTRACT In this paper, seismic analyses are performed of a reinforced concrete frame building with participating masonry walls carried out. The spectral method the Brazilian code – ABNT 15421:2006 was used to obtain lateral loads. equivalent diagonal-strut model employed simulate axial stiffness in frames, according different formulations founded literature. main purpose is evaluate difference...

In existing buildings, it may be necessary to repair, adapt, renew, relocate or demolish buildings and building parts that have come the end of their usage period due spatial, functional, technical economic obsolescence. After applications extend service life is great importance analyze dynamic behavior under soil-structure interaction earthquake loads obtain accurate results. this study, seism...

Infilled walls are the major non-structural elements which have significant effects on the seismic behavior of structures. The shape and strength of the brick elements are the main parameters affect the strength of the walls. In addition existence of openings may have a reduction effect. To increase the strength of the wall and to improve its behavior, the borders of the openings may be strengt...

Abstract The paper studies the influence of light weight aerated autoclaved concrete (AAC) partitioning walls to a medium height reinforced structure, in Bucharest (Romania). building is designed as framed structure with non-bearing AAC placed certain bays. There bearing full bricks masonry wall one Full are used because its high strength compared AAC. aim determine importance placement, both a...

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...
