Masonry infill walls are used as partition in reinforced concrete frames and are considered as a non-engineering structure for design and analysis purposes. The goal of this study is to compare different response parameters such as displacement, storey drift, base shear and ground overturning moment of a multi-storey RC frame structure with and without infill walls. For this purpose, a...
Waste management is a major issue worldwide. Glass is one of the solid wastes. Being non-biodegradable, it is inappropriate for landfill. One of the ways of disposing it off is its use in concrete for partial replacement of aggregates. In this study, tempered glass fines were used as partial replacement of aggregates in order to enhance the fire resistant properties of concrete. Concrete cubes...
Slope failures endanger the public safety and one of major hazard considered in mountainous terrain. In this paper, slope stability measures have been evaluated using the kinematic approach of limit equilibrium (LE). A case study of slope failure from Birham land slide, Murree, Pakistan has been modeled using LE based software SLOPE/W. In-sitboring tests are performed to collect labortary test...
Standard Penetration Test (SPT) and static cone penetration test (CPT) are the most widely used in situ tests to depict the soil stratigraphy and determine the geotechnical properties of the subsurface soils. The CPT leaps out because of its capability to trace the resistance continuously and due to its accuracy, it is still considered to be reliable than the SPT. The outcome of these tests is...
The study discusses the site-specific ground response analysis at a selected location in Peshawar University. The ground is modelled in one dimensional ground response analysis software DeepSoil using the standard penetration test results data. Based on the average shear wave velocity the site is stiff SD according to building codes of Pakistan. The input ground motion applied at the base of...
Cyclic Simple Shear (CSS) test is widely considered to best simulate vertically propagating shear waves and in-situ stress conditions. CSS test is always performed to generate reliable laboratory data for development and calibration of models in Geotechnical Earthquake Engineering design. Soil sample is laterally confined to simulate in-situ stress condition (k0). Stacked rings (SR) and...
Construction industry is constantly faced with a challenge to meet the everyday increasing demand of construction materials, with a growing concern in mind not to harm the environment. Cement is mostly costly material in concrete. Environmental pollution problems can be solved up to some extent using waste material in concrete The option of use of supplementary cementitious materials which are...
Abstract
This study focuses on the communication among various devices to share real-time information on smart devices. In this paper, we proposed a novel concept for domestic water collection and supply (DWCS) information sharing over a wireless sensor network (WSN), which uses mobile communication networks (MCN) for a Smart Mobile Ecosystem (SMES). This paper proposes a smart sharing of...
Housing plays a very important role in the human life and our society. Housing has a great social and economic impact on our lives and the way we live. It has direct and immediate effect on health, education, economy, environment, political and social life of any society. In today’s technologically advanced world, the quality of housing and its maintenance in a livable condition yet remains a...
Construction industry associates have started ascertaining that bid with smallest value does not declare maximum worth. Attaining a worth based procurement method is a challenge, mainly for the Pakistani public sector clients, who are still practicing the lowest bid award system. This research was to pursue construction specialists sentiments about the old-style bidding process and other...
This paper presents experimental investigations of Reinforced Concrete columns strengthened with steel strips and steel jacket under axial compression loading. Total of six specimens were prepared in the laboratory, out of which; 1) two columns were unconfined columns, 2) two columns were strengthened with steel strips and 3) remaining two columns were strengthened with steel jacket. All...
This paper presents permanent deformation behavior of untreated and lime treated base/sub base course materials at varying gradations and moisture conditions. Two types of base course gradations (NHA-A and NHA-B), three varying moistures i.e. optimum moisture content, optimum to dry condition and optimum to wet conditions and lime treatment of UGM investigated. Performance test (Permanent...
The growing human population around the globe imposes the need for highly sustainable and least energy intensive built environment. In the conventional building systems, enormous amount of energy is consumed for heating, ventilation and cooling applications to provide thermally comfortable environment for the occupants. Thermal insulations or energy storage materials are usually applied to...
The aims of present work is to develop a radically new stable, robust and computationally efficient structural analysis procedure capable of realistically and objectively predicting the nonlinear response of reinforced concrete structures. This procedure will be suitable for both research and practical applications and will be capable of effectively solving design optimization and reliability...
The seismic hazard at a site can be well quantified in term of fault rupture mechanism and site effect on seismic stress waves propagation. The input ground motion is an important parameter for the seismic characterization of ground response analysis and engineering structures. The presence of several active reverse faults in the vicinity of Peshawar Metropolitan city makes it vulnerable to...
The durability of concrete one of the most significant problems within the civil engineering community. Through careful design and the durability and long term performance of many concrete structures enhance by the use of Engineered Cementitious Composite (ECC) also known as High Performance Fiber Reinforced Cementitious Composite (HP-FRCC) or Benable Concrete. However, before implementing...
