This study presents an innovative 4D digital model that integrates Bridge Information Modeling (BrIM) with several types of data to defect detection in complex bridge structures. The promotes precise preparation, navigation, visualization, integration, and monitoring, enabling the identification defects, like material deterioration, condition changes, structural clashes components trusses. provides time-based access maps, allowing users explore changes over time predict future conditions....
In recent years, most cities have faced great demand for electricity supply due to rapid population growth and industrialization. Supplying sufficient electrical energy, while reducing greenhouse gas emissions, is one of the major concerns policymakers scientists all over world. Saudi Arabia, local authorities are increasingly aware necessity environmental impact nonrenewable energy by exploring alternative sustainable sources improving buildings’ efficiency. Recently, building-integrated...
The problem of metal-induced toxicity is proliferating with an increase in industrialization and urbanization. buildup metals results severe environmental deterioration harmful impacts on plant growth. In this study, we investigated the potential two ornamental plants, Catharanthus roseus (L.) G.Don Celosia argentea L., to tolerate accumulate Ni, Cr, Cd, Pb, Cu. These plants were grown Hoagland’s nutrient solution containing metal loads (50 µM 100 µM) alone combination a synthetic chelator,...
This paper presents a novel concept for significantly enhancing the strength and durability of ancient closed-box tombs. These tombs hold significant philosophical values, their architecture serves as valuable data source, providing insights into cultural stage society in which it was constructed. Throughout medieval modern times, clay bricks remained prevalent material tomb construction due to affordability design flexibility. However, these structures currently face neglect weakening,...
Abstract There have been a lot of claims made in the literature recently regarding physical characteristics nanofluids different flow systems, especially laminar regimes. The goal this study is to investigate two‐dimensional Jeffrey liquid that describes heat and mass transfer towards stagnation point over radial moving disc through Buongiorno nanofluid model. also aims impact transpiration velocity, magnetic field, zero flux incorporated fluid. reduces complicated partial differential...
This paper presents the flexural analysis of functionally graded plates resting on elastic foundations using new two-dimensional (2D) and quasi-three-dimensional (quasi-3D) higher order shear deformation theories. The main interesting feature this theory is that it proposes a displacement field with undetermined integral variables which involves only five unknown functions, unlike other normal theories, hence making easier to use. A parabolic transverse shape function satisfying zero stress...
Structural instability becomes an important concern in the composite plate safe and reliable design. In this research, a resistance analysis is carried out on plates made of hybrid material with without elliptical cutouts using finite element method. The carbon/epoxy/aluminum laminated are arranged following ordered manner [Al/(θ/-θ)/Al]. to buckling submitted uniaxial compression highlighted. Results indicate that given structural geometry, boundary loading condition stacking sequence, such...
The construction sector in Saudi Arabia has grown substantially the past three decades.It is expected that demand on concrete will increase by 10% 2019.The compressive strength considered to be most important property and it used as an indicator check quality of judge compliance with specifications.The main aim this research contribute evaluation region Hail Arabia.In study, a statistical strength, using 180 test samples after 7 28 days taken from different constructions city Hail, analyzed...
This paper compares the prestress losses as calculated by four different design codes; British standard CP110, Comite Europeen du Beton 70 and 78, American Concrete Institute 77 Prestressed method (PCI). The comparison is done determining total which take place in a rectangular prestressed concrete beam for both pre-tensioning post-tensioning systems. results show that are higher than those method, not usual case. It seems PCI may be required special structures or simply supported slender...
The paper describes the results of test carried out on OPC concrete and slag cement concretes. Ten blended slag-cement concretes, made with typical slags from four countries (United Kingdom, Belgium, South Africa Japan), are compared a control concrete. replaced 30 to 70% by mass. bobbin shaped specimens were used in direct tension 300x150 mm dia. cylindrical axial lateral strain tests. Poisson's ratio compression was determined as at ages 14 84 days. Concretes age days exhibits more...
Worldwide, concrete is the most preferred construction material. The steam curing method favored when there a need for accelerating strength. This paper presents study of compressive and flexural tensile strength subjected to eight different cures. In addition, stress-strain curve modulus elasticity were determined at age 28 days. test results show that after treatment, increases with maturity. A cycle pre-heating period gives better than without period. longer duration maximum temperature...
