Summary: A lattice transmission tower is considered as an overhead power line, a structure used in electric power transmission and distribution to transmit electrical energy across large distances. In this project, a specified model of a lattice transmission tower is designed based on applicable assumptions. This tower is a three-dimensional truss structure that angle elements containing L80x80x8 and L50x50x5 form the tower. The structural connections are bolted joint type (mostly in shear behavior) with M16 bolt. Although drawing preparation of bolted connection is a little harder than a welded joint, but makes the structural execution operations more comfortable.

Size: Retaining wall (18 meters long, 4.6 meters height, 8.2 meters width) - Pipe racks (~ 6 meters height)

Summary: Drought and unauthorized excessive extraction of water of the rivers in Khouzestan province, Iran and southeast areas in Iraq have caused water crisis at that region of Iran. These events have dried up some pastures and agricultural lands which has caused the dust crisis surrounding the province. To overcome the situation, the government has decided to revive and develop agricultural lands of the Khouzestan. In that regards, a project was defined in order to increase the capacity of the water distribution system for the palm trees to be revived. The system network scope was from the Karun River (Ahwaz suburban) to the Shadegan with the open channel. Therefore, a new pump station including four 250kW pumps was designed and connected to the existing ~80km channel. The main structural elements of this project includes a retaining wall and two types of pipe rack.

Summary: Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum. In this project, four similar circular clarifiers with a diameter of 28.4 meters were designed for the water treatment plant of the JahanAra-Arvand Steel Company. As a result of loose soil of the site, more than 120 rectangular piles with a length of nearly 21 meters were used under each clarifier. The number and length of the piles were estimated using the AllPile software. Professional studies were done by a geotechnical expert using the Plaxis software.

Summary: Both thickeners and clarifiers are used to settle solids in order to separate liquids and solids. A thickener will give a high density underflow while a clarifier will not. In other words, thickeners are used to concentrate solids, while clarifiers are used to purify liquids. The clarifier overflow is typically clearer than the thickener overflow would be. In this project, four similar circular thickeners with a diameter of 33.8 meter were designed for the water treatment plant of the JahanAra-Arvand Steel Company. The structural and geotechnical considerations for both thickeners and clarifiers are nearly the same.

Summary: At the beginning of water treatment process, it is required to distribute water intake among presedimentation tanks. In this project, a reinforced concrete structure named distributor pond was designed in order to distribute the water intake of the Karun River among four clarifiers. The river water enters the distributor pond through a large pipe dividing into four portions. Each portion is transported to the relevant clarifier using a buried pipe. After the initial treatment of the water in the clarifiers, the purified water is then flowed back through canals and is collected in the distributor pond, in a way that it does not mix with the incoming water from the river. Finally, the collected water is transported to the next unit (thickener) via a large pipe.

Location: Ahwaz, KHZ, IRAN

Size: 21 & 25 meters long (free span)

Main Structural Material: Steel

Software: CSi SAP2000 v18, AutoCAD® 2017 3D

Summary: In order that the water be transported via pipes in the industrial area of the Khouzestan Steel Company, three types of single steel pipe-rack were designed. In some situations, the pipeline designed tracks were crossing the road networks. In such situations, it was decided to design two types of steel truss conveyor (bridge). The free span of these bridges are 21 and 29 meters. Each of these bridges was modeled and designed in the CSi SAP2000 v18 according to the Iranian codes. In order to prepare technical drawings, the truss conveyors were modeled in the AutoCAD 2017, 3D with high precision. The 2D drawings were derived from these 3D models.

Size: ~100 meters long, 4.8 meters height, 4.5 meters width

Main Structural Material: Reinforced concrete

Software: CSi SAP2000 v17, AutoCAD® 2017

Summary: Due to development of water treatment plant at the Khouzestan Steel Company, pipelines had to cross one of the main entry gates of the company. It was decided to design a buried culvert in order to cross the pipes through the culvert under the ground. The designed culvert was nearly 100 meters long and its floor was 4.8 meters below the natural ground level. Some typical steel supports, which were connected to the concrete walls of the culvert, were designed for the pipes to lie on them.

Summary: Four electrical substation buildings with two types of plan were designed for the Khouzestan Oxin Steel Company. Each of these buildings included a diesel generator room, a transformer room and a LV/MV electrical room. The transformer room was covered by firewalls (fire resistant walls) which are also playing as structural shear walls. Electrical considerations were the main challenge in design of these RC structures and their foundations.

Course: Theory of Shells, Isfahan University of Technology

Software: MATLAB® R2016b, OpenSees 2.5.0

Summary: Elliptic paraboloid shells are a type of shells that can be used in roof covers or other applications regarding their architectural forms. In this project, a special case of shallow elliptic paraboloid shell, which has a rectangular plan, was considered. At first, the static flexural analysis under gravity load was investigated and then its modal analysis was carried out. After derivation of the force and deflection equations, which were in the form of Fourier series, the static analysis was programmed in Matlab. That calculation was numerically executed on two samples; however, the program can be applied to any other geometry of that specific type of shell. The modal analysis was done by programming in the OpenSees environment and the igen-value equations were solved for three problems. According to the functionality of this software, the programs written in its environment can be also applied to deep elliptic paraboloid shells.

Course: Repair and Rehabilitation of Structures, Sharif University of Technology

Main Structural Material: Reinforced concrete, Steel, and FRP

Software: MATLAB® R2012a

Summary: A computer program was developed that calculates bending moment, curvature, strain in rebar and strain in concrete for a rectangular cross section throughout the entire range of loading to failure. This program can be used to perform parametric studies on concrete beams reinforced with steel and fiber composite rebars, concrete beams strengthened with epoxy bonded fiber composite plates, and concrete columns strengthened for seismic forces with high strength fiber composite wraps. Four different types of material were used in the parametric study: concrete, steel, Glass-Fiber-Reinforced-Plastic (GFRP), and Carbon-Fiber-Reinforced-Plastic (CFRP). This project were accomplished through plots of moment versus curvature and moment versus strain in concrete, rebar, composite plate, and composite wrap.

Summary: A two-dimensional squared porous media containing two parts of aggregates and water was modeled. This media placed on an impermeable bedrock. Its left and right sides were covered by a specified water pressure. A specific distributed load were applied slowly to the top of the media causing completely drainage situation. Based on these descriptions, a computer program was developed to calculate the distribution of water pressure and effective stress in the mentioned media.
