Investigating the Behaviour of Plaster Mortared Rural Masonry Walls [PDF]

open access: yes, 2013
Turkey is located on the Alpine-Himalayan earthquake zone. %92 of its land is faced with earthquake hazard. Even in low intensity earthquakes, major damages have been observed in masonry structures.

Out-of-plane dynamic response of a tuff masonry wall. Shaking table testing and numerical simulation [PDF]

open access: yes, 2017
The out-of-plane dynamic response of a masonry element is investigated, both experimentally and numerically. The results of shaking table tests on a tuff masonry wall, subjected to harmonic acceleration histories, are presented.

The Layout and Size of an Early Pre‐Pottery Neolithic B Small Settlement Revealed by Geophysical Prospection at Harbetsuvan Tepesi in Southeastern Anatolia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT In Upper Mesopotamia, the transition from the Pre‐Pottery Neolithic A (PPNA) to Pre‐Pottery Neolithic B (PPNB) period, ca. 10 800–10 600 cal. BP, is marked by a series of changes in chipped stone industries, architectural forms, symbolic objects, regional distribution of settlements and long‐distance exchange networks among others.

Strengthening and Rehabilitation of U-Shaped RC Bridges Using Substitute Cable Ducts

open access: yesAdvances in Materials Science and Engineering, 2019
The presented paper deals with strengthening and rehabilitation of U-shaped reinforced concrete bridges from the period of 1905–1930 using post-tensioning, which is a suitable, reliable, and durable method.

The load bearing capacity of railway masonry arch bridges [PDF]

open access: yes, 2018
This paper deals with the way of calculating the load-bearing capacity of masonry arch railway bridges. It reviews the basic aspects of structural behaviour of these bridges, such as material non-linearity of masonry and interaction with the soil ...

Modeling Approaches for Masonry Structures [PDF]

open access: yesThe Open Civil Engineering Journal, 2014
Different scale approaches, micromechanical, multiscale and macromechanical or phenomenological, are presented to study the structural response of masonry elements. First, a micromechanical model is introduced and the masonry is considered to be a heterogeneous material, made of mortar and bricks joined by interfaces, where the mortarbrick decohesion ...

Digital documentation of railway tunnel inspection in Austria

open access: yesCivil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Impact of the self-healing agent composition on material characteristics of bio-based self-healing concrete

open access: yesCase Studies in Construction Materials, 2019
This paper investigates the composition of the biological self-healing agent based on its impact on material characteristics of concrete. A direct addition of the agent – a mixture of bacterial spores and nutrients – into concrete matrix has been ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Conservation of cultural heritage structures in seismic regions [PDF]

open access: yes, 2006
The paper addresses different aspects related to the conservation of cultural heritage structures, with a focus on: a) Behavior of masonry components under cyclic loading (tension, compression and shear); b) Behavior of stone masonry shear walls ...
