  Article on Covid-19 related issue in Iris Publishers COVID-19 pandemic is having many life-altering short and likely long-term effects. The COVID-19 pandemic has had a major impact on number of economical, ethical, legal, health services and social issues arise because of the virus rapidly spreading worldwide.  Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.  Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness. The best way to prevent and slow down transmission of covid-19 is protecting yourself by wearing mask and others from infection by washing your hands frequently and not touching your face. Most of the people recover from the acute phase of the disease. However, some people continue to experience a range of effects for months after recovery a...

  Iris Publishers - Open Access Journals of Civil and Structural Engineering Experimental and Numerical Evaluation of New Seismic Details for Connection of Post-tensioned Flat Slabs to Edge Steel Columns One type of structural systems that has received growing attention worldwide consists of flat slabs supported by steel columns. A key issue in these systems is the connection between slab and column. Although details for the connections of non-prestressed slabs are published frequently, but little details are reported for post-tensioned ones. In an experimental program, new details are proposed and examined for the connection of post-tensioned flat slab to edge steel column. The details include steel plates at the bottom and top of the slab, vertical stiffeners and vertical shear bolts. The connection is examined under cyclic lateral load test. The connection shows satisfactory seismic behavior, exhibits stable nonlinear response up to 3.5%drift ratio, and sustains gravity load cap...

  Iris Publishers - Journals of Civil and Structural Engineering Review of “Forensic Engineering, Legal Considerations, and Property Damage Assessment from Construction Vibrations” by D.S. Saxena, Prashanth Vaddu and Anu Saxena The paper contains a brief description of forensic investigations of failures and short information on a case history of damage to structures from construction vibrations [1]. The review focuses on the case history which is fully presented in Svinkin and Saxena [2]. The reviewer wishes to bring attention to proper evaluation of vibration effects on structures. Detrimental consequences of construction vibrations are not only topic for academic interests. These effects create meaningful practical problems. Each year, numerous structures, and residential houses among them receive damage from construction operations, and these consequences result in litigations. It is necessary to professionally manage construction vibrations, and sensible vibration limits are i...

  Iris Publishers - Scholarly Open access Journals of Civil and Structural Engineering Achieving A Higher Optimality for Lattice Steel Structures Utilizing A Multi-Layer Optimization Scheme Finding the optimum layout of a given structure that satisfies all the architectural requirements while maintaining the structural optimality has been of interest to the research community for many years. Concurrently, the structural design community has been making effort towards reducing the environmental impact through optimizing the structural design. However, the gap between the layout optimization in research and the structural design industry is yet to be significantly reduced. This research proposes a multilayer optimization framework, where the first layer is concerned with solving the layout problem using Simple Isotropic Material with Penalization (SIMP) topology optimization, and the second optimization layer determines the optimum structural elements’ design for the proposed layout ...
