Abstract:

i Abstract The Nockeby Bridge, in the western part of Stockholm, is a prestressed concrete bridge with an openable swing span of steel. The bridge was built during 1970 and should now be widened with 0.5 meters on each side. The concrete bridge deck is supported by two main-beams and cross-beams are located at the position of all supports. Previous studies of the bridge show that the torsional resistance is too low and the bridge needs strengthening while widened. The aim of this master thesis was to study and compare different strengthening methods for The Nockeby Bridge. Eight

Abstract:

Abstract Coping at work and job retention have been on the list of priorities of European countries for some decades. Vocational rehabilitation is a key measure for preventing work disability, but its possibilities have remained unused in many respects. Moreover, rehabilitation tasks are defined differently depending on the perspective taken. The purpose of this thesis is to determine the possibilities that arise from defining work-related rehabilitation tasks in a way that combines different perspectives and interests. The research questions are: 1) What were the impacts on working career and

Abstract:

In a digital world, users’ Personally Identifiable Information (PII) is normally managed with a system called an Identity Management System (IMS). There are many types of IMSs. There are situations when two or more IMSs need to communicate with each other (such as when a service provider needs to obtain some identity information about a user from a trusted identity provider). There could be interoperability issues when communicating parties use different types of IMS. To facilitate interoperability between different IMSs, an Identity Meta System (IMetS) is normally used. An IMetS can, at least

Одним з найважливіших вузлів поршневого компресора є штокове ущільнення, що забезпечує його герметичність. Тільки в газовій галузі США використовується понад 29 000 поршневих компресорів, в кожному з яких, в середньому, має чотири циліндри, що означає використання близько 160 000 систем ущільнення поршневих штоків. Через ці системи щорічно в атмосферу викидається 43,8 млрд. Фут.³ (1 226 млрд. М³) метану, що дозволяє розглядати їх як один з основних джерел емісії на компресорних установках при видобутку природного газу.

Abstract:

High wind events such as tropical cyclones, severe storms and tornadoes are more likely to impact the Australian coastal regions due to possible climate changes. Such events can be extremely destructive to building structures, in particular, low-rise buildings with lightweight roofing systems that are commonly made of thin steel roof sheeting and battens. Large wind suction loads that act on the roofs during high wind events cause premature failures of roof connections (fixings), leading to complete roof failures. Past wind damage investigations showed that the roof sheeting to batten conne

Furthermore, more detailed and sophisticated seismic vulnerability assessment approaches typically used for monumental buildings requi

Abstract:

The eco-friendly alternatives use is increasing momentum in a conscious effort towards sustainability. In this regards, the relevance and the economic value of using copper slag as a concrete aggregate are explored in this study in order to contribute towards metallurgical waste recycling. Emphasis is placed on the evaluation of the concretes strengthening prepared with copper slag contents and produced under four curing methods: water immersion, water spraying, plastic sheet covering and air-drying. In each curing case excluding for water immersion, was duplicated in indoors (i.e. in t

碩士<br>國立交通大學<br>資訊科學與工程研究所<br>103<br>Due to software quality issues, recent attacks on various systems are getting serious, and the software security issues therefore become an important research topic. These attacks on the software vulnerability will not only endanger the information infrastructure, but also impact the human safety. To improve the overall robustness of the system, we need a penetration test system to audit related systems. We have proposed the concept of the exploit toolchain to automate the whole process of fuzzing, exploitation, and post-exploitation integration with the me

Clay wall strengthen by ‘T’ steel plate at corner. (2.) Clay wall strengthen by angle steel ware. The test show the wooden frame strengthened by ‘T’ steel plate obtains 30% increase in max horizontal loading and strengthened by angle steel ware has 100% increas

According to research for restoration of wood members in Taiwan and investigation of current conditions of wood member, we discover that most partly seriously damaged wood members are replaced with new ones due to the lack of practical theory and difficulties encountered during restoration, and such method not only gives rise to secondary damage to historic sites but

Examinations afterwards showed that the buildings were insufficient in their shock resistance or unqualified for the shock endurance requirement set after the earthquake. However, the damages of the buildings were not serious enough for the buildings to be demolished. In fact, they can still be used without threats to public safety as long as they pass the process of seismic strengthening。 Therefore, the question of what should be the proper streng

When it expands with heat or contracts with cold, cracks will occur. When the cracks do occur, the concrete is imperfect and it will no longer be aligned. Therefore if we are able to understand further the effects of the cracks, it will help our research greatly. This research project will use the SAP2000 finite element method, Link and Plane stress to simulate reinforced concrete members. We will also consider concrete, steel bars,

HCP is a thin plate of Strain Hardening Cementitious Composite (SHCC) reinforced with Carbon Fiber Reinforced Polymer (CFRP) laminates applied according to the Near Surface Mounted technique (NSM). Due to the excellent bond conditions between SHCC and CFRP laminates, these reinforcements provide the necessary tensile strength capacity to the HCP, while the high post-cracking tensile def
