Training, motivation, and performance: The case of human resource management in construction projects in Mashhad, Iran

An enterprise’s productivity is closely correlated with its people and strategies; therefore, a forceful human resource management system is the most valuable asset of the current century construction companies. Purpose/design/methodology/approach: Based on a combination of literature review and questionnaire surveys, this paper explores the execution of construction workers training and motivation methods in HRM practices by the survey respondents’ companies and the effects on the companies’ performances. The research was conducted by sending 120 sets of questionnaires to the nominated companies and firms in Mashhad, Iran. A quantitative research approach was adopted requiring the development and dissemination of a questionnaire survey. The analysis method in this research is mainly descriptive and the type of investigation is co-relational study. Findings: The research exposes some barriers in the training and motivation of the construction workers and provides solutions for the government and companies in Iran. Also, it reveals the effects of unskilled labour on the quality of construction projects in Mashhad. Research limitations/implications: Future research should be under taken to address how companies and governments adapt to and shape the environmental and organizational settings in such a way that the context optimally stimulates workers motivation and participation in training courses and effects on increasing the quality of construction
Progressive Collapse Assessment of Multistory Reinforced Concrete[taliem.ir]

Progressive Collapse Assessment of Multistory Reinforced Concrete Structures Subjected To Seismic Actions

Progressive collapse is a catastrophic partial or total failure of a structure that mostly occurs when a structure loses a primary component like a column. Some international standards have started to consider progressive collapse resistance in various approaches. In this study, the ‘Unified Facilities Criterion’ guidelines were used in assessing the structure; these guidelines represent one of the codes that discuss progressive collapse using sophisticated approaches. Three-dimensional nonlinear dynamic analyses using the ‘Applied Element Method’ were performed for a structure that lost a column during a seismic action. A parametric study was made to investigate the effect of different parameters on progressive collapse. In this study, a primary structural component was assumed lost during an earthquake. The studied parameters were the location of the removed column in plan, the level of the removedcolumn, the case of loading, and the consideration of the slabs. For the study cases, it was concluded that the buildings designed according to the Egyptian code satisfies the progressive collapse requirements stated by ‘Unified Facilities Criteria’ (UFC) guidelines requirements with a safety factor of 1.97. Also, it was found that losing a column during a seismic action is more critical for progressive collapse than under gravity load. Finally, this study elaborated the importance of considering the slab in progressive collapse analysis of multistory buildings in order to include the significant catenary action developed by the slabs
