Though computer-mediated communication technologies such as immersive virtual reality (IVR) have recently shown considerable promise, their effectiveness as methods of communication among the participants in construction projects has yet to be systematically investigated. This study helps fill this gap via a detailed comparison of traditional face-to-face (FtF) discussion of Building Information Modeling (BIM) information displayed on a monitor screen against IVR-based communication with BIM inf...

Probabilistic risk assessment of slope failure evaluates the slope safety in a quantitative manner, which considers the failure probability and failure consequence simultaneously. However, risk assessment of unsaturated slope accounting for spatially variable soil-water characteristic curve (SWCC) model parameter and saturated hydraulic conductivity has been rarely reported. A probabilistic risk assessment approach is proposed in current study for rationally quantifying the unsaturated slope fai...

Using the post-tensioned (PT) elements can significantly plummet the persistent damages and the relevant costs to post-earthquake repair and maintenance, facing earthquake hazards. Rooted in a PT self-centering steel connection, the deformation and residual drift of the main members are limited to the linear elastic branch derived from existence of steel strands by omitting the gap between beam-column connections. The shape memory alloys (SMA) material has super elastic property according to the...

The sight distance at night is one of the most important driving safety factors. Sag vertical curves are one of the important elements of roads, which require a sufficient sight distance at night. The headlight sight distance is used for determining the length of the sag vertical curves. Presently, the parabolic curve is mainly used in symmetrical sag vertical curves. The present study aimed to propose the elliptic curve as a new alternative for the parabolic curve. An elliptic equation is devel...

Deformable solid projectiles undergo projectile mushrooming during impact and thus are different from rigid and soft hollow projectiles; however, limited work has been conducted on the impact of deformable solid projectiles on concrete targets. In this study, an explicit dynamic finite element procedure is employed to study nine existing experimental tests on the normal impact of a deformable solid (lead) projectile into a plain concrete (PC) slab. To correctly model the impact, both non-linear ...
A new drought index, the agricultural dry condition index (ADCI), was developed to combine various hydrometeorological variables associated with agricultural droughts. It was calculated by applying weights to the soil moisture, vegetation activity, and land surface temperature data, which are used to monitor agricultural droughts. The vegetation health index (VHI) and microwave integrated drought index (MIDI) are also used to monitor agricultural droughts; these were calculated using satellite i...

With excellent water permeability and high shear strength S, fiber-reinforced sand (FRS) is an ideal material for subgrades and has promising application prospects. In this study, the FRS were formed by adding the randomly distributed fibers to the sand specimens. Based on the triaxial consolidated drained tests, the effects of factors such as fiber content ζ, fiber length lf, relative density Dr and confining pressure σ3 on the S of FRS were systematically investigated. The test results showed ...

The aim of this paper is to investigate the influence of eccentric load and the presence of an opening near the column on the punching shear strength of reinforced concrete (RC) flat slab without shear reinforcement using analytical investigation and numerical simulations. A model based on the finite element method is proposed and its validation is confirmed in this study, by comparing the results with the existing experimental studies available in published literature. Twenty slabs supported di...

Undrained shear strength is a key parameter of clay and is popularly determined by penetrometers. Miniature penetrometers are preferred to estimate the undrained shear strength of clay for small-size model tests. In order to estimate undrained shear strength, an empirical factor should be established to correlate the tip resistance to the undrained shear strength. However, published data on miniature penetrometers are limited. This paper aims to evaluate empirical factors on miniature cone and T...

Doubtlessly hydraulic jump is a useful phenomenon in open channel flow such as rivers and spillways. As the most important characteristics of hydraulic jump, length, and sequent depth ratio play a key role in designing of hydraulic structures. The hydraulic jump length is one of the most important parameters, which cannot be calculated by mathematical analyses directly. In this context, several relations have been proposed to estimate the length and sequent depth ratio of the hydraulic jumps, bu...
