Letter from Caleb Gannett to Eliphalet Pearson, 6 December 1804

College steward Caleb Gannett wrote this letter to interim Harvard president Eliphalet Pearson outlining supply and labor needs for an on-time completion of the new college, Stoughton Hall, in Spring 1805. Supplies include lumber for staircases, corners, and doors; lime and hair for masonry; window weights, oil, paint, nails, hinges, and locks. Gannett also requests the services of a workman to complete a coating for the roof.

Fire behaviour of lightweight concrete units based on corn cob aggregate

Recent research works have concluded that corn cob may have interesting material properties, in particular, lightness, and thermal and sound insulation abilities. In this research work, corn cob is proposed as an alternative sustainable aggregate for lightweight concrete masonry unit (CMU) manufacturing. The corn cob requires to be granulated previously in order to obtain adequate particle size grade. Subsequently, the particles are wrapped in a cement paste with the purpose of reducing their water abortion and adherent capacities. CMU are current applied in the building of partition walls. The main goal of this research work consists on studying the fire behaviour of partition walls built with CMU of processed corn cob granulate (CMU-PCC).

A Coleção de azulejaria antiga da Faculdade de Belas Artes da Universidade de Lisboa : processo de inventário

This thesis presents the process of conducting the inventory of the old tiles collection of the Faculty of Fine Arts, University of Lisbon (FBAUL). This set can be divided into two major groups: the first is integrated in the building, the second consists of a set 2036 loose tiles with a pattern of decorative, ornamental and figuratively, some of which form panels of great value. Due to the existence of a wide variety of unknown provenance tile, stored at random, we feel the need to develop an inventory process, intended to safeguard and preserve these he-ritage objects whose existence was virtually unknown until the beginning of this work. This process continued working methodology started with the identification, photographic survey and labeling, with subsequent filling an inventory sheet. To obtain information about the loose tiles, it was essential to have a previous cleaning the mortar that prevented the reading of existing information in masonry, a process developed with the support of un-dergraduate students. After completion of the above process, we make the assembly of panels existing mostly very fragmented to give some iconographic references. In this process we identified 21 types of patterns belonging to the seventeenth and eighteenth centuries and 30 figurative and orna-mental panels. We realized then interconnections between them and the sets placed in situ around the building, and some of its tiles have been used to fill spaces or gaps. At the same time, we have created the inventory records, diagnosis and intervention, as well as a database for internal consultation - Excel - organized by a filtering system to allow quick search of all the tiles present in FBAUL. Finally, we will show a room to house the collection of loose tiles, making references to the ideal conditions of the outdoor environment and its packaging. Also we propose a very punc-tual removing some tiles embedded in the walls of the building which form part of panels composed of loose tiles, indicating a proposal to replace the other coherent and complete element belonging to the collection, preferably with a standard reason

Dimensionamento sísmico de edifícios baixos em alvenaria confinada

O facto de se ignorar a contribuição da resistência às forças laterais que solicitam as paredes de alvenaria das estruturas em zonas sísmicas é um tema que tem dado muito de que falar na engenharia estrutural. Em Portugal os projetistas preferem as soluções em betão armado pela sua ampla aplicação e bons resultados ao longo dos tempos. Perante o exposto anteriormente e com o objetivo de abrir possibilidades a novas alternativas que permitam de igual forma bons comportamentos estruturais, pensando na construção económica e com segurança, apresenta-se este estudo que propõe a aplicação de alvenaria confinada em zonas sísmicas de Portugal. A presente dissertação está composta por seis capítulos. No capítulo I apresenta-se uma introdução ao problema que permita ao leitor o enquadramento no tema, indicando de igual forma os objetivos específicos que foram precisos cumprir para chegar ao objetivo geral pretendido, isto é, a proposta duma metodologia de conceção de estruturas de habitação usando alvenaria confinada em zonas de risco sísmico em Portugal, delimitadas para edificações de 1 a 2 andares. Os requisitos gerais de ligação considerados baseiam-se no documento “SEISMIC DESIGN GUIDE FOR LOW-RISE CONFINED MASONRY BUILDINGS” os quais foram complementados com dados recomendados pelos EC 6 e EC 8 baseados na norma portuguesa. No capítulo II mostram-se antecedentes de estudos nacionais e internacionais da alvenaria confinada, assim mesmo encontram-se as bases teóricas com definições e requerimentos importantes a serem considerados no momento da conceção do projeto, ainda nesta seção indicam-se os passos para a aplicação do método de cálculo de esforços resistentes das paredes de alvenaria confinada (Método Simplificado), tal método foi aplicado e validado em modelos de elementos finitos desenhados com materiais e características sísmicas de comum aplicação em Portugal como se apresenta no capítulo III. No capítulo IV analisam-se os resultados obtidos, levando a que no capítulo V se descreva uma proposta de aplicação de alvenaria confinada em zonas de baixa sismicidade e alta sismicidade em Portugal. Finalmente no capítulo VI os resultados obtidos levam a concluir que em zonas de baixa sismicidade o dimensionamento de densidade de paredes é dependente das cargas gravíticas para edifícios de 1 e 2 níveis. No caso de zonas de alta sismicidade são as forças sísmicas as condicionantes. Ainda para edifícios de 2 níveis nestas zonas,a espessura mínima das paredes é de 0,20 m.
