Static and fatigue behavior of pultruded FRP multi-bolted joints with basalt FRP and hybrid steel-FRP bolts

2019-04-02 00:48:22 Keywords Bolted connections, BFRP, fatigue, Hybrid bolts, Static load,

This study investigates the effect of bolt types on the static and fatigue performance of basalt fiber-reinforced polymer (BFRP) multi-bolted double-lap connections. Three types of bolts are used: stainless-steel (SS), BFRP, and hybrid steel-FRP (HSFRP) bolts. Firstly, static tensile tests using steel single-bolted double-lap connections are conducted to determine the mechanical properties and failure modes of the proposed bolts. Secondly, ... Read more

INVESTIGATING THE EFFECTS OF CEMENT AND CEMENT KILN DUST AS A FILLER ON THE MECHANICAL PROPERTIES OF COLD BITUMINOUS EMULSION MIXTURES

2018-09-25 00:12:06 Keywords cold bituminous emulsion, cement kiln dust, SEM, , ITSM, fatigue, resistance to rutting,

The application of cold mixes is lagging behind in the research field, which is quite obvious in a developing country. Furthermore, cold mixes have more economic and environmental advantages than hot mixes. This is the principal motivation for the present research, which aims to improve the mechanical properties of cold mix asphalt. Ordinary Portland cement (OPC) and cement kiln dust ... Read more

Fatigue Analysis of FRP Strengthened RC Slabs Reinforced with Plain Bars Under Moving Load

2018-09-28 16:03:19 Keywords fatigue, CFRP, Reinforced Concrete, Slab,

In Japan, old RC bridge-deck slabs were economically designed by small thickness without considering the fatigue resistance. These slabs are subjected to a huge repetition of moving loads. Therefore, they are suffering from fatigue damage. This damage is more significantly observed than that of slabs reinforced with deformed bars. To extend their fatigue life, a suitable strengthening technique is required ... Read more

Fatigue analysis of RC slabs with plain bars and FRP strengthening based on bridging stress degradation concept

2018-09-28 16:05:57 Keywords fatigue, Slab, Reinforced Concrete,

The safety of construction in the long-term performance is the main goal of structural designers. An example is seen in reinforced concrete (RC) bridge deck slabs that have been subjected to a large number of load repetitions. Therefore, many numerical and experimental studies have been conducted to predict the fatigue life of these slabs. Most of these studies focused on ... Read more

Numerical simulation of FRP strengthening for RC slabs reinforced with plain bars under moving load

2018-09-28 16:12:42 Keywords fatigue, Reinforced Concrete,

There are many existing RC bridge slabs reinforced with plain bars, and they are suffering from a huge number of load repetitions due to heavy traffic. Therefore, a suitable strengthening technique is required to extend their fatigue life such as externally FRP sheets. To take full advantage of this strengthening technique, it is beneficial to use a numerical method to ... Read more

Fatigue analysis of RC slabs under moving load based on the bridging stress degradation concept

2018-09-28 16:20:18 Keywords fatigue, Reinforced Concrete,

From the numerical results and the experimentally verification, the following can be concluded: The fatigue behaviors of RC slabs reinforced with plain bars under moving load can be analyzed by this numerical method. The propagation of cracked elements due to its bridging stress degradation is considered as the main cause of fatigue failure. The proposed numerical method integrated the bond-slip ... Read more

Developing a numerical method for fatigue life prediction of RC slabs reinforced with plain bars

2018-09-28 16:23:21 Keywords fatigue, Reinforced Concrete,

The fatigue analysis of RC slabs reinforced with plain bars under moving load was conducted using this numerical method, and it shows a good agreement with the experimental results. Bond-slip effect of plain bars shall be taken into consideration for accurate fatigue life prediction. Read more

Fatigue analysis of RC slabs reinforced with plain bars subjected to moving load

2018-09-28 16:26:12 Keywords fatigue, Reinforced Concrete,

There is an increasing demand from researchers to simulate the fatigue behaviors of RC bridge slabs. Previous researches recorded that the fatigue life of RC slabs under moving load is lower than that under fixed pulsating load. Most of previous studies focused on the modeling of fatigue behaviors of RC slabs reinforced with deformed bars. But, many existing RC slabs ... Read more
