Mechanical Metastructure in Structural Engineering: A Short Review

In this paper a short review on the mechanical metastructure applied in civil and structural engineering is considered. This metastructure represents the macro version of the metamaterial which is a kind of composite. The main property of the mechanical metastructure is to mitigate and suppress vibration in systems. Depending on the configuration it represents vibration isolator or absorber which stops the low-frequency vibrations and forms an oscillation band-gap. Various types of mechanical metastructures with negative effective mass and negative stiffness are presented. In the paper the auxetic structures with negative Poison’s coefficient for vibration elimination are also considered. The future investigation in the matter is suggested.

Iris Publishers - Open Access Journal of Civil Engineering Structure, Building Envelop and Form integration in Architecture Contemporary Architecture is witnessing a significant transformation, because of developments in technology that is releasing architects from the use of static forms and historical construction methods, to the use of more dynamic forms that integrate elements of structure, building envelop and form in designs. This paper briefly examines developments in architecture over time, in order to situate and discuss the current emerging trend of integration. The article starts from exploring the history of architecture and the form of buildings in the different eras. It then moves on to discuss the contemporary trend in building form, structure and envelope integration, exploring some of the factors that are drive the trend and discussion of implication for the form of future architecture.

Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials | Osama K Adwan

Osama K Adwan |  Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials Research Article A common concern amongst civil engineers is producing a good quality concrete on-site. This paper reports results of a study carried out to examine the quality of normal strength concrete production in the southern region of Kingdom of Saudi Arabia (KSA) made from local coarse aggregate namely Basalt. As all data were analyzed and examined statistically using Chebyshev’s theorem and the Statistical Empirical Rule (SER) method presented herein. It is concluded that, the normal distribution of all test results -in terms of the quality of concrete mix- was strongly agree with Chebyshev’s theorem and ACI 318-14 section 5.6.3. In addition, these results were considerably better than the Statistical Empirical Rule (SER) method. Overall, these concrete mixes, in this investigation, with 28 days compressive strength of 35 MPa can be used confidently in concr...
