Abstract

Buildings located in seismic-prone areas require a high level of structural reliability to ensure safety and adequate performance throughout their service life. Conventional approaches to seismic structural design are generally deterministic and do not fully represent the uncertainties inherent in material properties, structural parameters, and seismic loads. This study aims to examine the application of a statistical approach in the reliability analysis of building structures subjected to earthquake loads. The research method involves modeling a reinforced concrete building structure in which material properties and seismic loads are treated as random variables. Structural reliability analysis is conducted using the First Order Reliability Method (FORM) and validated through Monte Carlo simulation. The results indicate that the statistical approach provides a more comprehensive evaluation of structural safety by quantifying reliability indices and probabilities of failure. Overall, the structure satisfies the minimum reliability criteria; however, several critical elements exhibit relatively lower reliability levels. These findings highlight the importance of integrating probabilistic approaches into the design and evaluation of earthquake-resistant building structures, particularly in regions with high seismic activity.

Abstract

Civil engineering construction projects are highly complex and therefore require effective planning and control, particularly in terms of cost and time. Project delays and cost overruns frequently occur due to suboptimal scheduling practices. This study aims to develop a mathematical model for cost and time optimization in construction project scheduling. A quantitative approach using mathematical modeling is employed, in which the scheduling problem is formulated as an objective function to minimize total project cost subject to duration constraints and precedence relationships among activities. An initial analysis is conducted using the Critical Path Method (CPM) to identify critical activities as the basis for optimization. The optimization model is solved using linear programming techniques with the assistance of optimization software. The results indicate that the proposed mathematical model is capable of producing a more efficient project schedule compared to conventional scheduling, as evidenced by a reduction in project duration and total cost. Furthermore, the time–cost trade-off analysis reveals the existence of an optimal project duration that results in minimum total cost. This study is expected to contribute theoretically to the development of construction management knowledge and practically as a decision-support tool for planning and controlling civil engineering construction projects.

Abstract

Truss structures are widely used in civil engineering design due to their efficiency in transferring loads through axial forces. However, conventional truss designs are often not optimal in terms of material utilization. This study aims to examine the application of the matrix stiffness method in truss structural analysis and to optimize structural design in order to achieve a more efficient configuration. The research methodology employs a numerical analysis based on the matrix stiffness method combined with a deterministic optimization approach. A two-dimensional truss structure model is analyzed to obtain axial forces and nodal displacements, which are then used as the basis for evaluating the objective function of minimizing structural weight under allowable stress and maximum displacement constraints. The results indicate that the application of the matrix method in the optimization process leads to a more uniform stress distribution and a significant reduction in total structural weight without exceeding the allowable strength and serviceability limits. Therefore, the matrix method is proven to be an effective and reliable approach for both analysis and optimization in truss structure design.
