This paper deals with the irregular profile of braced steel frame building in vertical direction with shear link bracing systems. The underlying fact of the paper is the effect of seismic force in braced frames with different types of irregularities including mass irregularity, mass discontinuity and overhanging mass. For each successive model, the position of shear link bracings has been fixed to make the study effective. This study has investigated the vulnerable effect of irregular profiles in steel frame buildings. To attain the behavior of each frame, linear time history analysis method has been adopted for the present study. FEMA356 standard has been used here for linear time history analysis. Investigations on different frames exhibit that regular profile with symmetry in mass is more efficient while using overhanging mass is detrimental considering the time dependent displacements and accelerations.

This paper deals with the irregular profile of concrete frame building along vertical direction comprising of mass discontinuity and overhanging mass. The underlying fact of the paper is the effect of seismic force in concrete frames with different types of irregularities including mass discontinuity and overhanging mass. For each successive model, the position of overhanging mass and mass discontinuity is kept variable to make the study effective. This study delineates the vulnerable effect of mass discontinuity and overhanging mass in concrete frame buildings. To attain the nonlinear property of each element of frame, pushover analysis method along with the equivalent static force method has been adopted for the present study. UBC97 code has been used here for linear static analysis while the parameters for nonlinear static analysis are arrogated from FEMA356 and ATC40. Investigations on different frames exhibit that the location of mass discontinuity and overhanging mass can be a key matter to avoid risks due to earthquake. While considering the design of such frames which have irregularities, designer must think about the position of irregularity. Basically, vulnerability increases in case of mass discontinuity if the irregularity is in lower stories. Moreover, vulnerability increases in case of overhanging masses if the irregularity is in higher stories.

This paper deals with the effect of environment in construction work in a particular area. Surrounding environment has immense effect in construction plan, site management, costs and implementation. On the contrary, it affects the workmanship's availability as well as material availability. Moreover, duration of a certain projects also depend on the impact of environment. Effect of climate, rainfall, humidity and temperature are the noticeable fact in the paper. This article represents the environmental effect of a particular place in Rajshahi city of Bangladesh which is known as RUET campus. Outcome of the investigation shows that the significant effect can be observed in the various ingredients of environment as well as construction project.
