This book reports on a comprehensive analytical, experimental and numerical study on the flexural response of post-tensioned masonry walls under in-plane loads. It explores an important mechanism in this new generation of structural walls, called “Self-centering”. This mechanism can reduce residual drifts and structural damage during earthquake ground motion, and is particularly favorable for structures which are designed for immediate occupancy performance levels. The book reports on the development and verification of a finite element model of post-tensioned masonry walls. It describes a detailed parametric study to predict the strength of post-tensioned masonry walls. New design methodologies and expressions are developed to predict the flexural strength and force-displacement response of post-tensioned masonry. Experimental study is carried out to better understand the behavior of post-tensioned masonry walls and also to evaluate the accuracy of the proposed design procedure and expressions. The book also includes an introduction to current research on unbounded post-tensioned masonry walls, together with an extensive analysis of previously published test results.

ABSTRAK
Paduan serbuk Cu-Sn merupakan paduan yang abnyak digunakan untuk bantalan berpori karena sifat-sifatnya yang tahan aus dan mudah diproduksi. Kandungan timah putih (Sn) pada paduan dapat mempengaruhi sifat-sifat paduan tersebut seperti porositas dan kekerasannya. Proses metalurgi serbuk mencakup pecampuaran dan pengadukan, kompaksi dan sinter.

Timah putih yang dipadu bervariasi pada 5, 10, dan 15%. Sedangkan tekanan kompaksi yang dikenakan sebesar 300MPa dan temperatur sinter 850°C. Sementara tu pengujian yang dilakukan meliputi densitas (kerapatan), porositas, kekerasan makro dan mikro dan kausan (wear). Kemudian produk sinter difoto mikro.

Pada penelitian ini diperoleh porositas terbuka produk sinter semakin banyak dan laju keausan semakin menurun dengan semakin tingginya kandungan Sn yang terdapat dalam paduan.

This book gives information on non destructive techniques for assessment of concrete structures. It synthesizes the best of international knowledge about what techniques can be used for assessing material properties (strength) and structural properties (geometry, defects). It describes how the techniques can be used so as to answer a series of usual questions, highlighting their capabilities and limits, and providing advices for a better use of techniques. It also focuses on possible combinations of techniques so as to improve the assessment. It is based on many illustrative examples and give in each case references to standards and guidelines.

This book develops the basic elements needed for both fracture research and engineering practice. The emphasis is on continuum mechanics models for energy flows and crack-tip stress- and deformation fields in elastic and elastic-plastic materials. In addition to a brief discussion of computational fracture methods, the text includes practical sections on fracture criteria, fracture toughness testing, and methods for measuring stress intensity factors and energy release rates.

This book discusses the main mechanical features of masonry buildings and the peculiarities that affect their structural behaviour. It also examines technical information regarding accidents that have occurred in recent years in the Metropolitan Region of Recife, along with the historical records of these events, followed by indications of the causes for the collapse. The book offers extensive experimental results that make it possible to identify the contribution of several mortar rendering layers to the load capacity of the tested specimens. Lastly, it explores the factors that influenced the load capacity of the tested specimens.
