 Iris Publishers - Journal of Civil and Structural Engineering The Emerging Need for Civil Engineering Design to Embrace a New Systems Approach to the Solution of Complex Problems in Rapidly Changing Technical and Political Landscapes Abstract Traditional solutions to engineering problems have utilized long standing methods developed using deterministic algorithms to arrive at optimal solutions to problems which are relatively easily defined. In a modern, rapidly changing technical and political landscape, these traditional methods do not react rapidly enough to emerging outcomes dependent on interactions between multiple variable systems. The author considers the efficacy of traditional approaches when applied to solving modern complex problems and suggests that there is much our industry could gain by adopting the types of techniques being developed in other fields of expertise. Introduction Picture a scene of a wandering explorer hiking through a mountainous unexplored landscape...

  Iris Publishers - Journals of Civil and Structural Engineering Review of “Forensic Engineering, Legal Considerations, and Property Damage Assessment from Construction Vibrations” by D.S. Saxena, Prashanth Vaddu and Anu Saxena The paper contains a brief description of forensic investigations of failures and short information on a case history of damage to structures from construction vibrations [1]. The review focuses on the case history which is fully presented in Svinkin and Saxena [2]. The reviewer wishes to bring attention to proper evaluation of vibration effects on structures. Detrimental consequences of construction vibrations are not only topic for academic interests. These effects create meaningful practical problems. Each year, numerous structures, and residential houses among them receive damage from construction operations, and these consequences result in litigations. It is necessary to professionally manage construction vibrations, and sensible vibration limits are i...

  Iris Publishers - Scholarly Open access Journals of Civil and Structural Engineering Achieving A Higher Optimality for Lattice Steel Structures Utilizing A Multi-Layer Optimization Scheme Finding the optimum layout of a given structure that satisfies all the architectural requirements while maintaining the structural optimality has been of interest to the research community for many years. Concurrently, the structural design community has been making effort towards reducing the environmental impact through optimizing the structural design. However, the gap between the layout optimization in research and the structural design industry is yet to be significantly reduced. This research proposes a multilayer optimization framework, where the first layer is concerned with solving the layout problem using Simple Isotropic Material with Penalization (SIMP) topology optimization, and the second optimization layer determines the optimum structural elements’ design for the proposed layout ...

  Iris Publishers - Peer Review Journal of Civil Engineering GIS and Processing data with SIMUS This is a case with a real structure from a road project in Africa, but with data changed for confidentially reasons. The purpose of this paper is to demonstrate how a powerful tool such as the Geographic Information System (GIS), may be used jointly with a Multi Criteria Decision-Making (MCDM) method. This problem is addressed using both methodologies in two different and sequential steps, when the first precedes the second. Thus, GIS produces information regarding consideration spatial interrelations of all features considered. The MCDM uses that information aiming at the selection of the best alternative. In this case, GIS provides spatial information on a certain area combining about 15 different themes involving environment, social and natural features such as villages, rivers, forests, swamps, etc. Four potential paths where detected, subject to these mentioned features, and then, ...

 Iris Publishers - Journal of Civil Engineering Project and Design of a Special Agricultural Warehouse Developed in Phases in Valencia (Spain) This article describes the developing phases to build warehouses for a Pomelo Company at Valencian County (East of Spain). The warehouses are remarkable because they did not have many intermediate columns. Spatial and lightweight solutions are adopted and described. In the Projects also natural ventilation and lighting have been considered with a successfully result. Erection conditions and Regulations have been taken also account. It has been an inspiration motive for other consultants. Read More...

  Iris Publishers - Peer Review Journal of Civil Engineering Rethinking the Collaboration of Civil Engineering and Human Geography In response to the global shift in technology, a heavy burden of responsibility is placed on the sciences to act in the best approach. This study reviews from a different perspective about the collaboration of two fields of science: engineering and human geography. In the management of construction on a large scale, it becomes essential for engineers in development planning and the construction process that consider social and environmental impacts. Thus, the involvement of other fields of knowledge that understand the interaction between humans and the environment becomes a crucial point in efforts to preserve the environment and natural resources. Human geography, which studies human interaction with the environment, will play an essential role in bridging for civil engineers to understand better the social and environmental impacts that arise in a co...

  Iris Publishers - Open Access Journal of Civil Engineering Hydraulic Facilities Characteristics along the Upstream Lanchang River According the current hydropower development schedule in upstream Lanchang River, numbers of hydraulic power plants with height over 300 meters will be built in the western region of China. These hydraulic power plants would be in crucial situation with the problems of high water head, huge discharge and narrow riverbed. Spillway is the most common structure in power plant which is used to drainage and flood release. According to the previous research, the velocity would be reaching to 55 m/s and the discharge can reach to 300 m3/s.m during spillway operation in the dam height over 300 m. The high velocity and discharge in the spillway may have the problems such as atomization nearby, slides on the side slope and river bank, Vibration on the pier, hydraulic jump, cavitation and the negative pressure on the spill way surface. All these problems may caus...

 Iris Publishers - Journals of Civil Engineering Recent Bushfire Impact on Timber Bridges in Northern New South Wales This paper provides preliminary observations and comments following recent field inspection of a number of fire-damaged bridges in northern New South Wales (NSW). The fire event has been described as unprecedented, at least in living memory, with over five million hectares burnt in NSW from September 2019 to late January 2020, comprising mostly national parks and state forest, but also many neighbouring properties and houses. The impact on infrastructure has been profound, with at least three government schools destroyed and numerous timber road bridges damaged or destroyed in eastern NSW. Some roads have been closed for months and are still closed. These events will have long lasting implications. It is clear that changes will be needed to successfully adapt to altering externalities in the future. Read More... Full Text For More Articles in  Current Trends in...

  Iris Publishers - Peer Review Journals of Civil Engineering The Core Value of Modern Mass Transit Systems The mass transit system is a behemoth in a metropolis. It requires a lot of investment, human and material resources, but there is no way to try samples. Once the construction of the hardware facilities is completed, it will be difficult to modify them in the future. Rarely two lines are the same. It is not possible to fully replicate the specifications and meet the needs of the line. Therefore, the core value base strategy is very important. As long as the core values are correct, the system established will meet the needs of local society and industry. Read More...
