The stiffness of masonry infill walls is commonly neglected in design practice Reinforced Concrete (RC) structures. In fact, the wall may significantly influence seismic performance and dynamic behavior RC buildings. this research, to structural a three-story frame investigated. addition, possible application friction-based support also studied. Full 3D non-linear time history analysis conducte...

Recycled concrete brick (RCB) is manufactured by recycled aggregate processed from discarded concrete blocks arising from the demolishing of existing buildings. This paper presents research on the seismic performance of RCB masonry walls to assess the applicability of RCB for use in rural low-rise constructions. The seismic performance of a masonry wall is closely related to the vertical load a...

PURPOSE This work investigated the proton tissue-equivalence of various 3D printed materials. METHODS Three 3D printers were used to create 5 cm cubic phantoms made of different plastics with varying percentages of infill. White resin, polylactic acid (PLA), and NinjaFlex plastics were used. The infills ranged from 15% to 100%. Each phantom was scanned with a CT scanner to obtain the HU value...

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

According to the masonry standard the compressive strength is basically dependent on factors such as the mortar strength and the relative values of unit and mortar strength. However interlocking brick has none or less use of mortar. Therefore there is a need to investigate the behavior of masonry walls using interlocking bricks. In this study a series of tests have been conducted; physical prop...

Masonry in one form or another is used in most areas of the world that are prone to interplate or intraplate earthquakes. Masonry structures constructed from traditionally fired or stone bricks have one characteristic that sets them apart from most other structures. If a masonry building is well constructed, it can last for millenniums. Research in the field of Damage Mechanics has identified t...

An accurate evaluation of the non-linear behavior of masonry structural elements in existing buildings still represents a complex issue that rigorously requires non-linear finite element strategies difficult to apply to real large structures. Nevertheless, for the static and seismic assessment of existing structures, involving the contribution of masonry materials, engineers need reliable and e...
