Direct Displacement-Based Seismic Design of Unbonded Post-Tensioned Masonry Walls

From: ACI Structural Journal | Date: September 1, 2007| Author: Wight, Gavin D; Kowalsky, Mervyn J; Ingham, Jason M | Copyright information

Post-tensioned masonry walls exhibit desirable seismic performance characteristics due to increased in-plane strength and the absence of residual lateral displacement at the conclusion of seismic loading. The direct displacement-based design (DDBD) approach aims to provide a method whereby a structure may be designed to achieve a predefined level of lateral deformation under a predefined level of earthquake intensity. This paper details the development of a DDBD procedure to assist in the des...

Shaketable Testing of Rectangular Post-Tensioned Concrete Masonry Walls
ACI Materials Journal ; The in-plane seismic response of partially grouted post-tensioned concrete masonry (PCM) walls with unbonded tendons is investigated by means of shaketable testing. The principal intent of this study was to validate use of this wall system for residential construction, before the first PCM house is

Blast resistance of FRP-strengthened masonry walls
Concrete ; In recent years, accidental domestic gas explosions and concerns about terrorist attacks have increased interest in strengthening masonry walls against blast effects. The purpose of this article is to investigate the static out-of-plane behaviour of masonry walls strengthened with fibre-reinforced
Thermal behavior of masonry walls in Istanbul.
Construction and Building Materials ; Abstract This study is based on thermal performance analysis and evaluation of masonry wall configurations with respect to thermal comfort and energy conservation with the software DOE-2.1E. The analysis comprises the comparison of the annual heating and cooling loads of the masonry wall
A modified on-site water chamber tester for masonry walls.(Statistical Data Included)
Construction and Building Materials ; Abstract The paper begins with a review of the currently available on-site water-tightness tests for masonry walls. The development of a modified on-site water chamber tester is reported. Results derived from experiments using this new tester are discussed. The results show that the leakage rate is
