“…It expands when it absorbs more water and creates the potential to exert enough force on a building or other structures to cause damage. In addition, Tabuk city exposed too many flash floods, mainly from large drainage basin of Wadi Na'am, Al Baqqar and Dab'an which covered an area of about 2860 km 2 This study showed the importance of characterizing geotechnical properties and hydrological elements as part of a comprehensive environmental analysis for future urban planning. Based on the hazard map of the expansive soils of Tabuk city, it found that the western side of the city lying in the upstream of the small basin and the subsurface layers is composed of sandstone.…”

“…Damages to infrastructure caused by expansi-ve soil movement have been widely reported in many countries such as Australia, China, United States, India and South Arica [2]. In America, the economic loss of the expansive soil question approximately amounts to above $15 billion every year [3] [4] [5] more than twice the damage from natural disasters.…”

Due to global climatic changes, flash floods are followed as a yearly disaster with high magnitude of influence. During the years 1981, 1988, 2010, 2012 and in January 2013, Tabuk city, northwest of Saudi Arabia suffered huge flash floods. These are major factors affecting on the swelling behavior of expansive Tabuk shale. The examined geotechnical properties of the surface and subsurface lithology of the sedimentary deposits distinguished Tabuk city into three zones. The expansive zone is spread in the middle and the non-expansive zones are distributed in the east and west of the city. The Watershed Modeling System (WMS) and Hydrologic Engineering Center (HEC-1) models were used to delineate and identify the drainage system and basin morphometry, where flash floods and accumulation of water might take place. Integration between geotechnical distribution maps of the expansion soil and surface hydrological data in terms of runoff maps was done. It has been identified the whereabouts the soils which have expansion characteristics and areas prone to flooding and surface runoff. They are helpful in defining the hazard zones map. Based on this map, it can be avoided constructions on the risk neighborhoods such as Al Qadsiyah, Al Maseif, Arrwdah, Al Nakhil and Al Rajhi. Also, it can suggest that the western side of Tabuk city is suitable for future urban extension. These results will help planners and citizens to create alternative development scenarios and determine their impact on the future urbanization patterns. Moreover, the direction of surface runoff flow or storm water discharge should be away from the expansion soil areas. Therefore, constructing dams on the outlet of the high-risk basins, south of Tabuk city is an important solution to control flash flood events, as well as increase groundwater recharge.

“…At present, unsaturated soil mechanics is still relatively new in the geotechnical engineering field and there is little software available for simulating the fully coupled volume change behavior of expansive soils, let alone any well‐established program for simulating the fully coupled soil–foundation–structure system as proposed in the previous paper. As a result, as discussed in the previous sections, no one has yet been able to simulate all the factors influencing the behavior of residential buildings in a single program . By contrast, the fully coupled thermal stress analysis and the coupled thermal–mechanical interaction between deformable bodies have been investigated for a long time and there are many well‐established finite element method software packages such as ABAQUS and ANSYS.…”

“…The major limitation on past research simulating residential building on expansive soils is that the factors mentioned earlier have never been simultaneously investigated in a single analysis (e.g., [5,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]). The building, the foundation, and the soils make up the complete system.…”

“…Sophisticated commercial computer programs for solving the coupled hydro-mechanical stress problem for unsaturated soils are scarce, and lack coupled hydro-mechanical stress-jointed elements and general shell elements. Indeed, no researcher has included as many factors as proposed in this paper in the simulation of residential buildings built on shrink-swell soils in a single system (e.g., [5,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]). This is another reason for our incomplete understanding of foundation behavior on shrink-swell soils.…”

SUMMARYShrink-swell soils can cause distresses in buildings, and every year, the economic loss associated with this problem is huge. This paper presents a comprehensive system for simulating the soil-foundation-building system and its response to daily weather conditions. Weather data include rainfall, solar radiation, air temperature, relative humidity, and wind speed, all of which are readily available from a local weather station or the Internet. These data are used to determine simulation flux boundary conditions. Different methods are proposed to simulate different boundary conditions: bare soil, trees, and vegetation. A coupled hydromechanical stress analysis is used to simulate the volume change of shrink-swell soils due to both mechanical stress and water content variations. Coupled hydro-mechanical stress-jointed elements are used to simulate the interaction between the soil and the slab, and general shell elements are used to simulate structural behavior. All the models are combined into one finite element program to predict the entire system's behavior. This paper first described the theory for the simulations. A site in Arlington, Texas, is then selected to demonstrate the application of the proposed system. Simulation results are shown, and a comparison between measured and predicted movements for four footings in Arlington, Texas, over a 2-year period is presented. Finally, a threedimensional simulation is made for a virtual residential building on shrink-swell soils to identify the influence of various factors.

The use of prefabricated systems can alleviate the inadequate housing and skilled workers in most developed countries by expediting required construction time, reducing material wastage, decreasing the effect of weather impacts, minimizing unexpected costs, skilled labor dependence, and construction hazards. The full potential of prefabricated construction is yet to be realized in part due to most advancements being focused on its superstructure. The development of prefabricated substructures for lightweight buildings needs to consider the susceptibility to damage induced by the shrink‐swell movement of expansive soils causing significant global financial losses. Prefabricated substructures should have robust connections in discontinued regions to transfer forces and moments. Due to these issues, the aim of this study is to develop a connection for prefabricated raft substructures of single‐detached dwellings on expansive soils using a combined soil‐structure contact analysis and strut‐and‐tie model approach. The developed substructure system was validated using experiments and further investigated through numerical simulations. The developed prefabricated connection was observed to have satisfactory performance, potentially overcoming most construction limitations of conventional monolithic cast‐in‐place raft substructures, such as faster, safer, and more sustainable construction, while providing comparable strength and serviceability.
