Article
Full-text available
The reduction in the shear strength accompanied to the increasing in the section depth is characterised as size effect, assuming that all parameters are kept constant. Such behaviour is controlled by many factors. The geometry of the element formed between the load and support points is one of those factors that need to be highlighted. Owing to tha...
Conference Paper
It is well known that concrete is the most popular material for construction. It was reported that the production of one ton of Portland cement emits almost one ton of carbon dioxide gas into the atmosphere, contributing significantly to global warming. Annually, around 1.35 million tons of greenhouses gases are being emitted due to the manufacturi...

Non-destructive tests (NDTs) represented one of the solutions that aid the engineers to evaluate the strength of materials. However, the results obtained using such tests still questionable as they may be affected by different factors. One of these factors is the presence of steel reinforcement in concrete. An experimental investigation is presente...

Preserving natural resources and implementing the concepts of sustainable engineering to approach the zero waste concept helped in reducing the detrimental environmental effects in the last two-decade. Proposed re-using of Ground Granulated Blast Furnace Slag (GGBS) as an alternate solution is to get rid of them and profit from them concurrently. I...

Full-text available
The Ordinary Portland Cement (OPC) is one of the major ingredient utilized for the manufacture of concrete. The manufacturing of cement includes the release of huge amounts of CO 2 gas as a main contributor for greenhouse influence and global warming. Several researchers have investigated the characteristics of OPC concrete utilizing cementitious m...

The technique of replacing the cement with other alternative materials focuses on the production of materials with similar performance and reduced environmental impacts relative to traditional cement. The main aim of this study is to investigate the effect of replacing the cement content with high volume of Pulverised Fuel Ash (PFA) on the mechanic...

This work study the impact of partial cement replacement by high volume Rice Husk Ash (RHA) on some characteristics of cement mortar like compressive strength and flexural strength at different ages. In this research, RHA was used in three different ratios (20, 40, and 60)% as a cement substitution and the findings were compared with control mixtur...

In the present research, ten simply supported reinforced concrete beams having a rectangular cross-section were cast and tested up to failure under the action of two-point loads. Eight of these beams were designed to contain horizontal construction joints (HCJs) of different number and location in the beam while the other two beams had no construct...

Environmental pollution and the relatively high cost of waste disposal have been a major focus for scientists around the world, leading researchers to find a solution to reuse waste materials in different applications. Additionally, landfills are considered one of the biggest crisis facing the Iraqi government. Therefore, this study aims to present...
Article
Full-text available
Researchers awarded a considerable attention to progressive collapse analysis in recent years to avoid the partial or entire failure of structures. General Service Administration guidelines (GSA) established the base to deal with such catastrophic failure. For multi-story building, these guidelines proposed column removal scenario in which one or m...
Article
In the current investigation, four reinforced concrete beams with square cross sectional area were poured and tested up to failure under the action of three-point loads. Three of them were designed to contain small web openings of different shapes, square, rectangular and circular while the other beam had no openings (control beam) for the purpose...
Article
Full-text available
This paper focuses on the flexural impact behaviour of steel I-beams with rectangular web openings. Published studies on impact resistance and design requirements of perforated steel beams are limited. To shed light such a topic, detailed non-linear three-dimensional finite element models (FEMs) were developed using ABAQUS. Rigorous validation proc...
Article
Full-text available
High loading rates may produce in structural frames due to some actions, such as explosions or debris impact. The response of structural members to such abnormal loadings should be investigated to provide comprehensive knowledge of their capability to resist impulsive forces. Beam-column joint is considered one of the most important structural comp...
Article
Full-text available
This paper presents a 3D nonlinear finite element analysis on simply supported steel beams subjected to impact load. The modelling was developed to simulate the beams and the models developed were validated against the corresponding experimental results with good correlation. Parametric studies were achieved to study the steel beam with web opening...
Article
Cold asphalt emulsion mixtures (CAEMs) can be said to produce a reduced environmental impact and lower energy consumption in comparison to hot mix asphalt (HMA). They are also safer to use as there is no heating involved in the production and application of such mixtures. However, CAEMs are described as inferior to traditional HMA because of weak e...

Abstract: A parametric study is presented in this paper based on validated finite element models that were built in the companion paper that investigates the behaviour of two types of beam-column connections named flush plate connection (FPC) and partial depth end-plate connection (PDEPC) under quasi-static and lateral impact loadings. In the curre...

An extended study on the lateral impact response of end-plate beam-column connections is presented in this paper. A parametric study is presented based on validated finite element models that were built in the companion paper that investigates the behaviour of two types of connections named flush plate connection (FPC) and partial depth end-plate c...

Article
The behaviour of concrete filled steel tube (CFST) columns has been investigated intensively against lateral and axial impact loading. However, there is a lack of knowledge on the impact response of the connection between such the column and steel beam. In order to close this gap, the most common connections with a partial depth end plate (PDEPCs),...
Article
The behaviour of different steel beam to column connections has been studied intensively against static and seismic loading regimes. However, there is a lack of knowledge on the response of such connections against impact and blast. In order to close this gap, the most common connections with partially depth end plate (PDEPCs), as a simple connecti...
Article
This research represents experimental work for investigation of the influence of utilising Ground Granulated Blast Furnace Slag (GGBS) and High Calcium Fly Ash (HCFA) as a partial replacement for Ordinary Portland Cement (OPC) and produce a low carbon cementitious material with comparable compressive strength to OPC. Firstly, GGBS was used as a par...
Conference Paper
This paper presents a method for modelling and analysing end plate beam-to-column connections to obtain the quasi-static behaviour using non-linear dynamic explicit integration. In addition to its importance to study the static behaviour of a structural member, quasi-static behaviour is largely needed to be compared with the dynamic behaviour of su...

Corrosion inhibitors studies were carried out on carbon steel rebar samples under different pH conditionsand in the presence and absence of chloride ions in solution. A known amount of sodium nitrite was added asan inhibitor and the mechanism of inhibition was studied by tracking both the thermodynamic and kineticproperties of the system. The studi...

Dear Colleagues,
I am trying to analyse a 3D frame in SAP2000. Please, let me know if the time history analysis can be performed using displacement control in SAP2000.

Question
It is needed sometimes to seed a thickness with different number of elements in Abaqus. How to do that for structured meshing in 3D modelling?
Question
If you validate your FE models against experimental work under impact load. How can you use that model to predict the blast response to avoid doing experiments again?
