Full textEarth is still used as a building material to construct houses in Africa. One of the most common techniques is the masonry of sun dried or kiln fired mud bricks with earth mortar. Although this technique is cheap and allows the self-construction, the bricks vary largely in shape, strength and durability. This leads to weak houses which suffer important damage during floods and seismic events. A solution which has been proposed in the last decades is the use of drystack masonry with stabilized interlocking compressed earth blocks (ICEB). These blocks are manufactured by compacting cement stabilized earth in a manual or hydraulic press into a mould and then air cured for 28 days. The resulting blocks present uniform shapes, higher values of strength and durability and lower embodied energy than the traditional bricks. The material properties of ICEBs has been researched extensively, but little has been concluded with respect to the structural behaviour of these masonry dry-stack systems. Motivated by the above reasons, this work focused on the study of ICEBs to be used in dry-stack masonry of one storey houses in regions with moderate seismicity. Malawi was selected as the case study country. The mechanical characterization of the masonry was made by first studying the material properties of the blocks. Parameters such as compression and flexural strength, the Young’s modulus and compressive and tensile fracture energy have been determined through laboratory tests. In a second phase, masonry specimens were tested to determine the compressive strength, shear behaviour of the dry joints and shear behaviour of full scale walls. Finally, to study the behaviour of a real structure under seismic action, a small masonry mock-up of a house was tested on a shaking table. The results of the tests showed that it is possible to produce ICEBs of sandy soils with sufficient strength. The tests of shear walls revealed that the shear strength of this masonry is low, but comparable to that of other earthen walls. The walls also showed high values of ductility and behaviour factor. The shaking table test showed that the mock-up resisted without significant damage peak ground accelerations (PGA) of 0.2 g, which are equivalent to those expected for frequent earthquakes in Malawi. It also showed that moderate damage can be expected for rare earthquakes with PGAs of 0.3 g and that near collapse would occur at almost twice that value. The behaviour factor was of 1.5, which is the maximum permitted by the Eurocode 8 for unreinforced masonry. The knowledge gained in the several phases of this work was used to develop a manual for building ICEB houses.
A terra tem sido usada como material de construção para a edificação de casas em África. Uma das técnicas mais comuns é a alvenaria de tijolos de terra, secos ao sol ou cozidos em forno, com argamassa de terra. Embora esta técnica seja barata e permita a auto-construção, os tijolos variam muito de forma, resistência e durabilidade. Isto leva a casas de fraca qualidade, que sofrem danos importantes em caso de inundação ou evento sísmico. Uma solução que tem sido proposta nas últimas décadas é a alvenaria de blocos de terra compactada com sistema de encaixe (ICEB). Estes blocos são produzidos por compactação de terra estabilizada com cimento numa prensa manual ou hidráulica e são deixados a curar ao ar. Os blocos resultantes apresentam formas uniformes, valores de resistência e durabilidade superiores e energia incorporada mais baixa que os tijolos tradicionais. As propriedades dos ICEBs tem sido investigada intensivamente, mas pouco tem sido concluído em relação à definição do comportamento estrutural destes sistemas de alvenaria de junta seca. Motivado pelas razões acima expostas, este trabalho focou-se no estudo de ICEBs para serem utilizados em alvenaria de junta seca de casas com um andar em regiões de sismicidade moderada. O Malawi foi o país escolhido como caso de estudo. A caracterização mecânica da alvenaria foi conseguida estudando-se primeiro as propriedades materiais dos blocos. Foram determinadas experimentalmente várias propriedades mecânicas, tais como resistência à compressão e flexão, módulo de elasticidade, e energia de fratura em compressão e tração. Numa segunda fase, foram ensaiados provetes de alvenaria para caracterizar-se a resistência à compressão, comportamento ao corte das juntas secas e comportamento de corte de paredes à escala real. Finalmente, um pequeno modelo de uma casa foi ensaiado em mesa sísmica para se estudar o comportamento de uma estrutura real sob ação sísmica. Os resultados dos ensaios mostraram que é possível produzir ICEBs com resistência suficiente, a partir de solos arenosos. Os ensaios das paredes à escala real revelaram que a resistência ao corte da alvenaria é baixa, mas comparável à de outras paredes de terra. As paredes também apresentaram valores elevados da ductilidade e do fator de comportamento. O ensaio de mesa sísmica mostrou que o modelo resistiu sem danos significativos a acelerações pico do solo (PGA) de 0.2 g, que são equivalentes às esperadas em sismos frequentes no Malawi. Também se mostrou que podem ser esperados danos moderados para sismos raros com PGAs de 0.3 g e que o quase colapso só ocorreria para cerca de o dobro deste valor. O fator de comportamento foi de 1.5, que é o máximo permitido pelo Eurocódigo 8 para alvenaria não reforçada. O conhecimento obtido das várias fases deste trabalho foi utilizado para se desenvolver um manual para a construção de casas de ICEBs.

Full textThis thesis presents the findings on empirical study of dry-stack masonry. Dry-stack masonry refers to a method of building masonry walls, where most of the masonry units are laid without mortar in the joints. Of late (since mid eighties) in modern construction, dry-stacking or mortarless technology is increasingly becoming popular because of its advantages. The construction industry is acknowledging the need to accelerate the masonry construction process, as the traditional method is labour intensive and hence slower due to the presence of a large number of mortar joints. Early attempts were made to increase the size of masonry units (block instead of brick), thereby reducing the number of mortar joints, wherein the use of bedding mortar imposed constraints on the number of courses to be constructed in a day. Elimination of bedding mortar accelerates construction; thereby reducing cost, variation due to workmanship and generally small pool of skilled labour is required in dry stacking. Dry-stack masonry is a relatively new technology not yet regulated in the code of practice and therefore very limited information on the structural behaviour of the masonry is available. This project is based on the investigation of the HYDRAFORM dry-stack system, which utilises compressed soil-cement interlocking, blocks. The system is now widely used in Africa, Asia and South America. The main objective of the project was to establish through physical testing the capacity of the system to resist lateral load (e.g. wind load), vertical load and dynamic load such as earthquake loading. In the first phase of the project investigations were conducted under static loading where series of full-scale wall panels were constructed in the laboratory and tested under lateral loading, and others were tested under vertical loading to establish the mode of failure and load capacity of the system. Series of control tests were also conducted by testing series of wallettes to establish failure mechanism of the units and to establish the flexural strength of the system. Finally the test results were used for modelling, where load prediction models for the system under vertical loading and under lateral loading were developed. The theoretical load prediction models were tested against the test results and show good agreement. After the load capacity was established the next step in the study was to further improve the system for increased capacity particularly under dynamic loading. The normal Hydraform system was modified by introducing a conduit, which allows introduction of reinforcements. Series of dry-stack seismic systems were constructed and initially tested under static lateral loading to establish the lateral load capacity. The second Phase of the project was to investigate the structural behaviour and performance of the Hydraform system under seismic loading. A shaking table of 20 tonnes payload, (4m x 4m) in plan was designed and fabricated. A full-scale plain dry-stack masonry house was constructed on the shaking table and subjected to seismic base motions. The shaking table test was performed using sine wave signals excitations starting from low to very severe intensity. A conventional masonry test structure of similar parameters was also constructed on the table and tested in a similar manner for comparison. The tests were conducted using a frequency range of 1Hz to 12Hz and the specimens were monitored for peak accelerations and displacements. For both specimens the initial base motion was 0.05g. The study established the mode of failure of the system; the structural weak points of unreinforced dry-stack masonry, the general structural response of the system under seismic condition and the failure load. The plain dry-stack masonry failed at 0.3g and the conventional masonry failed at 0.6g. Finally recommendations for further strengthening of system to improve its lateral capacity were proposed.

Full textExperimental study of five full scale masonry wall panels subjected to prescibed pre-compressive vertical loading and increasing in-plane lateral loading is discussed. All five walls were constructed using interlocking mortarless load bearing hollow concrete blocks. The behaviour of wall in term of deflections along the wall height, shear strength, mortarless joint behaviour and local and overall failures under increasing in-plane lateral loading and pre-compressive vertical loading are reported and analysed. Simple strut-and-tie models are also developed to estimate the ultimate in-plane lateral capacity of the panel walls tested. The results indicate that, as the pre-compressive load increases, the in-plane lateral load capacity of walls increases. All walls tested failed due to diagonal shear and/or moderate toe crushing depending on the level of the pre-compressive load. The proposed strut-and-tie models were able to give reasonable predictions of the walls tested.
