Climate Change and Research Challenges in Civil and Structural Engineering

Current Trends in Civil & Structural Engineering

Actually, research in civil and structural engineering needs more worldwide collaboration to find solutions for many challenges related to climate change. Particularly, efforts must be focused on the development of modern design codes based on reliability concepts, calibrated from quantitative risk analysis for adapting to, and mitigating the impacts of natural disasters such as storms, sever earthquakes, strong winds …etc. These codes are the basis for engineering design and play an important role in decision making about the performance of structures over their working life. The consideration of reliability concepts in structural and geotechnical engineering is widely recognized because they are based on probability theory that enables the impact on safety and serviceability of uncertainties in both materials behavior and calculation models. Especially in the field of geotechnical engineering, the uncertainties in the soil properties are relatively high. Therefore, efficient probabilistic techniques are necessary to define reliability levels for structural design. Current design codes, based on partial safety concepts, define the target reliability for different structures (onshore, offshore) depending on the desired safety levels, however worldwide research efforts and developments are needed for engineering practice of risk and reliability analysis. In addition, they should be calibrated and adapted to the actual environmental loading related to climate change.

Iris Publishers- Open Access Journal of Civil Engineering

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...
