Abstract:

Thesis (MScEng (Civil Engineering))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: Pre-cast sections have the advantages of structural efficiency, better quality control and less construction time, which enable them to be widely used in building structures. The connections of pre-cast buildings play a vital role for the stability and strength of structures. Nowadays, more attention is drawn to the aesthetical appearance of building structures, especially by architects. The Hidden Corbel Connection (HCC) was then developed to make the building structures stable and aesthetically

Abstract:

The study investigates experimentally and theoretically the behaviour of an internal precast concrete beam-column connection, where both the column and beam are discontinuous in construction terms. The aim was to modify the behaviour mechanisms within the connection zone by introducing a beam hogging moment resistance capacity under dead loads and limiting the damage within the connection. This is to offer permanent dead load hogging moments that could counterbalance any temporary sagging moment generated under sway loads, enhance the rotational stiffness, balance the design requirements for t

Abstract:

Several connection details have been developed for the connection of precast cap beams to precast columns in Accelerated Bridge Construction (ABC) applications. Currently, the suggested details involve some form of either reinforcement or portion of the precast column to penetrate inside the cap beam. Such details present many challenges in the field, such as necessitating bundling of reinforcement in the cap beam or creating a congested reinforcement arrangement. Furthermore, closer inspection of some of the test data indicates that for currently used details, cap beams could sustain some dam

This study investigates the experimental and theoretical behaviour of an exterior precast concrete beam-column (PCBC) connection.

The aim of this study was to develop a ductile exterior PCBC connection, which will be comparatively simple to construct on site and be suitable for building structures in seismic zones. Five PCBC connection specimens (namely: P1, P2, P3, P4 and P5) were tested. Two principal factors were investiga

Jointless bridges are advantageous in removing mechanical joints which are a known cause of bridge deterioration. Elimination of joints provides a smoother riding surface and removes the possibility of de-icing salts penetrating the deck and corroding the deck reinforcing and underlying bridge superstructure. Jointless bridges are traditionally constructed by monolithically casting the entire bridge deck on beams after they have been erected. However, this process requires extensive in-field formwork and lengthy traffic closures. The Texas Department of Transportation proposes a new method of

Abstract:

O atrativo estético proporcionado pela forma arredondada é o fator que na maioria das vezes determina a utilização de estruturas tubulares circulares. É crescente a concepção de pórticos formados por colunas tubulares e as tradicionais vigas de seção I. Esse tipo de ligação ainda é pouco estudado no Brasil, e esse trabalho busca avançar no entendimento do comportamento estrutural dessas ligações. Foram realizados estudos analíticos, numéricos e experimentais em quatro configurações de ligação, com diafragmas externos transversais, chapa de alma, soldas, parafusos e enrijecedor. Avaliou-se a re

Abstract:

Este trabalho tem como objetivo analisar a influência da laje de concreto armado em uma ligação viga-pilar misto mediante um estudo experimental e uma modelagem numérica. A ligação considerada é constituída por uma viga de aço unida a um pilar misto preenchido através de barras rosqueadas que trabalham como parafusos passantes. Esse tipo de ligação já foi investigado em trabalhos anteriores, mediante análise experimental em modelos que não incluíam a laje, resultando em uma indesejável ruptura dos parafusos. A análise da ligação completa, com a presença da laje de concreto tornando a ligação u

Esta pesquisa consiste de uma investigação acerca do comportamento estrutural de ligações entre viga de seção I e pilar de seção tubular circular em situações de pilar de canto e de pilar solicitado por quatro vigas simultaneamente (pilar central). A associação entre a viga de seção I e o pilar de seção tubular circular remete à análise de ligações com comportamento complexo. A partir da análise numérica, via Método dos Elementos Finitos com os softwares ANSYS® e TrueGrid® foi avaliado o comportamento momento-rotação e parâmetros como resistência, rigidez inicial e ductilidade das ligações.

Abstract:

Na construção de novas estruturas ou mesmo durante sua recuperação, a velocidade de construção influencia de maneira significativa, não apenas nos custos, mas também pelo potencial efeito nocivo (ruído, poluição, problemas no transito de veículos e pessoas, etc.) advindo da construção. Assim, para a construção, é desejável um período de construção tão breve quanto possível. As estruturas mistas de aço e concreto correspondem satisfatoriamente a essa necessidade, pois tanto os elementos de aço quanto os de concreto podem ser pré-fabricados industrialmente, ficando apenas as etapas de içamento e

Abstract:

While the progressive collapse mechanisms of concrete and steel buildings have been widely researched, limited studies have been carried out on mass timber buildings. Experimental testing under given loading scenarios of the entire system or a representative large part of it, may be required to extend the knowledge and improve design rules. However, due to the limited laboratory space and budget restrictions, fullscale tests are rare and may not always be possible. In steel and concrete, tests are frequently performed on scaled down systems. Since timber is an inhomogeneous material, interpret

In this study the influence of the stiffness of beam-column connections on the structural behavior of multi-storey buildings in reinforced concrete was investigated.
