(Civil Project) A 3D Finite Beam Element for the Modelling of Composite Wind Turbine Wings

The main purpose of this thesis is to develop a 3D beam element in order to model wind turbine wings made of composite materials.
The proposed element is partly based on the formulation of the classical beam element of constant cross-section without shear deformation (Euler-Bernoulli) and including Saint-Venant torsional effects for isotropic materials, similarly to the one presented in Batoz & Dhatt. The main novelty consists in the addition of the coupling between axial and bending with torsional effects that may arise when using composite materials.

(Civil Project) The Holistic Value-Added Approach to Sustainable Development

Sustainable design and engineering is in great demand in cities all over the world. As a result, design and engineering consultancies have to continue finding ways to capitalize on sustainable developments responsibly.
Implementing a strategy to reduce the friction between the human-ecology and economic imperatives is a major step. Amongst Ramboll’s Nordic sustainable perspectives, the Swedish perspective can be  innovative enough to reduce this friction that can stand in the way of the comprehensive sustainable project mission, which is profitable and value-added.
But can this comprehensive and holistic Nordic approach, intended to link stakeholders into a positive project dynamic be applied  effectively enough under unique country-specific contexts? A strategy that incorporates a framework to understand and value the intangibilities of sustainability and fine-tuned for the different conditions and unique contexts of where projects are built can help by creating positive  synergies between stakeholders.

(Civil Project) Green Skyscraper: Integration of Plants into Skyscrapers


This research has been emphasized on integration of plants in skyscraper design which play a vital role for the energy conservation by the building as well as improving the living quality into these vertical cities. Throughout the work it has been studied to establish the necessity of planting to incorporate into skyscrapers, for the well being of our economy, society and the environment.

(Civil Project) Structural behavior of notched glulam beams reinforced by means of plywood and FRP


Nowadays, timber is widely used in construction industry thanks to its availability and good properties. The use of solid (sawn) timber is not always proper since it is only available up to certain dimensions. Therefore, the so-called Engineered Wood Products (EWPs) have been introduced tocope with the different design needs of structures.

(Civil Project) Housing Development


The project consists in nine single-family detached houses with a residential activity building. This project is designed to suit the inhabitants who live in Halmstad. It includes green areas to walk, playing areas and gardens. However, for many months the weather in Halmstad is relatively cold, therefore, the project includes a common building where residents can play sports, relax, meet even sunbathe. This will enhance the status of the area.

(Civil Project) FEM Modeling of Concrete Gravity Dams


This project is an analysis of two different concrete gravity dams. One of the dams, the Baozhusi Hydropower Station, is a fully functional concrete gravity dam situated in the Sichuan province in the Peoples Republic of China. This dam reopened again after its upgrading, which was finished in 1998.

(Civil Project) Optimization of Best Management Practices for Watershed Planning


Increases in nutrient loading are an on-going problem in many watersheds including the Chesapeake Bay watershed. Best management practices (BMPs) are used to reduce loadings to watershed tributaries. However, budget constraints often make determining the most effective nutrient load reducing BMP set a complex task.

(Civil Project) Rehabilation and Maintenance of Road Pavements using High Early Strength Concrete


The vast amount of civil infrastructure in the United States includes an extensive stretch of road networks. From an economic point of view it is more cost effective to maintain the already existing pavements rather than building new ones. A large proportion of the traffic delays on these road networks are caused by road closures and closures of individual lanes for pavement maintenance purposes.

(Civil Project) Building a Water-Energy Nexus Modelling Tool for New York City


Increasing demands for energy and water from a growing urban population challenges resource availability and infrastructure capacity in cities worldwide. Planning for infrastructure systems development to meet growing demands has traditionally been done separately, not regarding that these systems are in many aspects interlinked.

(Civil Project) Effect of Dead, Live and Blast Loads on a Suspension Bridge



Bridges in America are of special importance. The analysis of these bridges should be carried out for different loading conditions. Bridges are normally designed for dead load, live load and other occasional loads. American Association of State Highways and Transportation Officials (AASHTO) have specified for the ship impact, seismic vulnerability and also against vehicular collisions. But there are no definite structural design criteria for the bridges under typical blast loadings.

(Civil Project) The Design of an Overpass Crossing on Railway in Mirny, Arkhangelska Oblast, Russia



Bridge design and construction practice in former USSR, especially Russia, is not much known to the foreign engineers. Many advanced structural theories and construction practices have been established. In 1931, Franklin D. Roosevelt said, “There can be little doubt that in many ways the story of bridge building is the story of civilization. By it, we can readily measure a progress in each particular country.”

(Civil Project) Capacity assessment of a single span arch bridge with backfill


The aim of this project is to assess the load carrying capacity of the Glomman Bridge outside of the Swedish city Örebro. The Glomman Bridge is an unreinforced concrete single span arch bridge with backfill. The bridge was constructed in 1923 on assignment from the Swedish National Railways (SJ).

(Mechanical Project) Effects of Mach Cruise Number on Conventional Civil Jet Aircraft Sizing



The objective with this work was to examine the effects of fitness ratio, lift over drag, lift coefficient at cruise, winglet span, wing sweep angle, wing aspect ratio, wing area and weights with respect to Mach number for a conventional business jet capable of 18 passengers. The cruise speed study range from Mach 0.88 to 0.99.

Vertical Displacements in a Medium-rise Timber Building (Civil Project)


The history of timber buildings in Sweden entered a new era when the authorities decided to lift the ban on constructing more than two-storey timber buildings in Sweden. This change in legislations has contributed to the emergence of timber construction during the last decade.

(Civil Project) Energy storage systems: an approach involving the concept of exergy


This project deals with thermal energy storage systems (TES), which are devices used to store and re-lease thermal energy with a time delay. In the first part of the study, the state-of-art of the TES systems is discussed, grouping the different technologies on the basis of the energy storing process.

(Civil Project)Integrated Analysis of Vertical Alignments and Speed Profiles for Rail Transit Routes


Frequent accelerations and decelerations for rail transit trains adversely affect in the major performance measures of travel time, tractive energy consumption and braking wear between stations. A dipped vertical alignment between rail transit stations provides trains some added advantages from gravity in accelerating as well as in decelerating.

(Civil Project) Behavioral Study of Ultra High Performance Concrete Girders


Ultra High Performance Concrete (UHPC) is one of the newer and superior classes of concrete that can be used to develop improved bridges capable of meeting the present and future traffic, environmental, maintenance and economical requirements. Developing on the superior material properties of UHPC, the research discussed herein studies the behavior of UHPC when used as a bridge girder material.
Four optimized girders have been cast and studied for various early age as well as long term properties such as early age shrinkage, transfer length, creep behavior and shrinkage under steam treatment. Data has been recorded through vibrating wire gages installed at strategic locations within each girder before they are cast.

(Civil Project) Risk-Based Bridge Maintenance Strategies


The aging of bridges and traffic volume increase result in deterioration of bridge conditions and consequently increased risks to bridges and users. Highway agencies in the United States face challenges because of lack ofsufficient resources to maintain bridges in good conditions.
