Morphometric Indicators Analysis of Relief for the Engineering Design Problems

In the practice of engineering design, the most demanded morphometric indicators of the relief, such as the average slope of the territories and the general slope of the entire territory. Based on these indicators, decisions are often made on the acceptability (adequacy) of a project for a selected territory. The article presents a comparative analysis of the existing methods of triangulation and spatial interpolation of the relief based on primary sources. The selection of primary source data is based on a rectangular regular network, which is applicable in the practice of engineering preparation of territories to various tasks of vertical planning. The reasonable problem points of the preliminary relief analysis are given for making optimal decisions on the existing methods of the digital relief model. In this regard, a new method of morphometric analysis of the relief was proposed, based only on the primary data, regardless of the choice of the method of triangulation and spatial interpolation. New definitions are given, such as: the quarter of the surface, which is a unit of the selected territory and the plane of the quarter, based on the average values of the source data of the quarter. On the basis of the proposed method, the “Geoanalyzer” software complex has been developed and some program modes of operation are given that help to visually and numerically analyze the topography of the selected territory.

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...
