The behaviour of roof gable walls under the effect of earthquake load

Abstract

Abstract. In this study, the effect of earthquake loads on roof gable walls and the behaviours of these roof gable walls are investigated. In preparation of the study, two experiments on cradle roof system which gets and does not get any loads off the roof members were carried out in all. The experiments were performed on the shaking table in Earthquake Research Department of General Directorate of Disaster Affairs. Through the experiments, some considerable results were obtained on the behaviours of roof gable walls under the effect of horizontal dynamic loads. The results obtained at the end of these examinations are given and discussed. Furthermore, suggestions to make the brick gable walls more reliable against the loads of earthquake are given. When the results of the experiments were generally taken into consideration, it was realized that the gable walls in both roof systems would partly or completely collapse even under the effect of a little horizontal dynamic load.

Shaking table tests on strengthening of masonry structures against earthquake hazard

“…Indian researcher Jagadish (2002) used a pendulum and a free vibration table o simulate the earthquake forces on the masonry houses. Altin et al (2005) and Kamanli and Balik (2010) used a more simplistic shaking table to test the different strengthening strategies on the masonry houses.…”

Altın et al (2005) and Kamanli and Balik (2010) used a more simplistic shaking tablet o test the different strengthening strategies on the masonry houses. This paper discusses the effectiveness of masonry strengthening techniques The scope includes construction of one reference and eight strengthened identical 1/10 scaled one storey masonry houses and dynamic testing of specimens on uniaxial shaking table.…”

Behaviour of 3D RC frames placed at different angles on shaking table

“…For educational purposes, models with scale factor 1:10 or less [3][4][5][6][7] are being used in construction laboratories for shake table testing. There we can observe different modes in the building, while we can observe damage types in buildings in case of models with a scale factor greater than 1:10 [8][9][10]. However, the shaking table experiments with samples scaled at 1:1, 1:2 and 1:3 are both expensive and large as a system [11][12][13][14].…”

Hardware-software system for simulating and analyzing earthquakes applied to civil structures

“…Different works have proposed the use of earthquake signals to excite civil structures, due to the fact that it permits analysis of the structure behavior under real conditions (San Bartolome et al, 2004;Dolce and Cardone, 2006;Johnson et al, 2008;Van de Lindt and Potts, 2008;Kamanli and Balik, 2010). Synthetic signals are mainly used to obtain the modal parameters of a structure and to determine its fatigue life; sinusoidal sweep or pure sinusoidal are the most widely used (Zivanović et al, 2006;Dominguez et al, 2007;Ibrahim and Reynolds, 2008;Ersubasi and Korkmaz, 2010).…”
