A Comparison Study of a Novel Self-Contained Electro-Hydraulic Cylinder versus a Conventional Valve-Controlled Actuator—Part 2: Energy Efficiency
2019
This research paper presents the second part of a comparative analysis of a novel self-contained electro-hydraulic cylinder with passive load-holding capability against a state of the art, valve-controlled hydraulic system that is typically used in load-carrying applications. After addressing the control design and motion performance in the first part of the study, the comparison is now focused on the systems&rsquo
Dimensjonering av slank balkong i Ultra-High Performance Fibre-Reinforced Concrete
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 As part of the fifth and final year in civil engineering at University of Agder, this master’s thesis has been composed. This report was written during the spring semester of 2017. The purpose of this thesis was to dimension a slim balcony in UHPFRC. Nor Element wanted to be able to produce slim balconies in their own production facilities. Nor Element is currently producing balconies, but these have thicker cross sections. This master’s thesis involves a literature study and a dimension process. In the literature study the relevant guidelines and Eurocodes are presented. The study contains relevant formulas and recommendations needed t…
Rehabilitering av antikvarisk betongkonstruksjon fra perioden 1926-1938 : Vurdering av rehabiliteringstiltak og restkapasitet for Ingierstrand bad, b…
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Traditionally restoration of antiquarian concrete constructions has been a prominent topic in Norwegian context. This topic has been given more attention, as more concrete constructions and reinforced concrete constructions have been preserved. In this thesis a case-study were done of Ingierstrand bad. A central part of the restoration of antiquarian concrete constructions is to control the capacity of the concrete against occurring stresses. We have in this thesis theoretically controlled the capacity of the standard being used during projecting and building, and that of today’s standard. We suggested the actions of restoration we thin…

Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Fiber reinforced composites have many good properties, but also many applications that make it vulnerable to accidental loads, like impact damage and fire. The problem with this is that minor and larger damage can be difficult to observe and a challenge to inspect on the spot. All materials exposed to fire, or high temperatures will expand, which can cause instability and large deformations. Several studies have examined the behavior of composites under these typical accidental loads individually, but none or very few have investigated when they occur simultaneously or the overall effect they provide. To address the problem in this thes…

Krysslaminert massivtre som bærende struktur i modulbaserte studentboliger : FEM analyse av modulbaserte studentboliger i krysslaminert massivtre
2021
Master's thesis in Civil and structural engineering (BYG508) This is a master’s thesis conducted at the University in Agder as the finishing work for the subject BYG508 and the master program in civil and structural engineering. This report seeks to examine some possibilities that exists with the use of Cross-laminated timber, CLT for modern student accommodation with the use of Finite element method, FEM software. With the increased interest in new building materials,it is important to examine the possibilities that lies within these materials and experiment and analyze to determine their usefulness. Based on the client’s wishes, the research question for this report was determined to be: …
Effektivisering av betongelementproduksjonen : Ved bruk av tegningsløs armering og prefabrikkert forskaling
2018
Masteroppgave bygg BYG508 - Universitetet i Agder 2018 Technology evolves exponentially, and technological aids follow the same course. Manufacturing methods in the construction industry are also constantly evolving, and a company that wishes to follow this development is Contiga. Contiga is the leading supplier of prefabricated concrete elements in Norway. For several years they have used the Lean methodology, and with this methodology mapped where in the manufacturing process there is room for improvement. Prefabrication has become more and more common in recent years, and innovative solutions and methods have also come. In the process of manufacturing the concrete elements, models are co…

Master's thesis in Civil and structural engineering (BYG508) Ultra-High Performance Concrete (UHPC) was developed in research to increase the strength and durability of concrete. The material has shown remarkable ductility, durabilityand strength properties in laboratory tests, but has not beenmuch tested in practice. This master thesis presents an experiment to investigate the durability of UHPC in two marine environments in view of the risk of rebar corrosion. Factors under consideration are cover depth and crack width to observe how this will influence the penetration of aggressive substances that can cause corrosion. To investigate the corrosion state and chloride content, electrochemic…
