This paper exhibits an experimental study on dynamic response of a single pile under dynamic load which comes from motor placed on cap pile called a vibration source. This study used the effect of the dynamic movement of vibration on one pile, collapsible soil (gypseous soil) used in this study with 30% gypsum content. The experiment is performed in a dry and soak state. A solid steel pile with a slenderness ratio of 27 was inserted into the soil after preparing it in layers in a steel container (30 * 30 * 60) cm. The test was performed under a dynamic response to the different frequencies 10, 15, 20, and 25 Hz. The results showed that the speed, acceleration and displacement increase with increasing frequency of the vibration source in addition to that the values of speed, acceleration and displacement amplitude are less in the case of soaking compared to their values in the dry state.

At present, the relevant researches of Glulam columns in China are mainly restricted to short columns. In order to study the mechanical properties of long columns under axial loading, an experimental study on five different slenderness ratios of Larch Glulam columns was carried out. With slenderness ratio changing, the variations of experimental data such as axial strain, lateral deflection at mid-height, ultimate bearing capacity, and peak strain were comparatively analyzed. The failure pattern and failure mechanism of long columns were discussed. The results indicate that the ultimate bearing capacity of Larch Glulam columns gradually decreases as the slenderness radio increases and the failure mode is gradually converted from strength failure to instability failure. The ultimate load reduction factor is obtained by regression analysis based on the experiment results of Larch Glulam short columns. The basis for design and application of Larch Glulam columns are provided.

In this article, through changing the parameters of the slenderness ratio lambda and axial compression ratio of n, the eight experimental study of steel tube concrete bending members with circular cross section. To explore different slenderness ratio of lambda concrete-filled steel tube under low cycle loading, the damage form of artifacts, deflection change, the relationship between the load and strain, load (P) and displacement (Δ) curve, the axial deformation and stiffness degradation curve, displacement ductility coefficient and the change of parameters such as energy consumption, thus further elastic-plastic seismic response analysis of concrete filled steel tubular structures. Got by test data of load P - displacement Δ relation curve and stiffness degradation curve, the displacement ductility coefficient, the total energy consumption. To get round steel tube reinforced concrete member seismic performance is good, the ductility damage.

<span lang="EN-US">The objective of evaluating User Experience (UX) in this era of technology is to enhance the user satisfaction. Earlier applications were built with the aim of reducing the work of users. But with the evolution of the technology, the emergence of new gadgets and new trends in the information technology, the applications had to be more user-centric. The primary objective of this research is to evaluate the user experience of web applications based on different UX parameters using different techniques and given a rating. Each of these ratings are combined to determine the overall rating of UX for the web application. Also, the secondary objective of this research is to provide suggestions or recommendations based on the ratings to improve the UX of the web applications. An experimental study was conducted and the results show a significant improvement. Areas of further enhancements have also been identified and presented.</span>

While alternate modes of delivery in education are assuming importance, it is imperative to train the pre service teachers to use the web resources to maximise learning experience. This paper attempts to study the inquisitive nature of student teachers of south India to use the e resources named as e quest. This experimental study uses blended learning strategy as a treatment for experimental group and conventional method of teaching for control group with respect to some personal variables. The findings prove that blended learning strategy increases the e quest score of pre service teachers irrespective of their prior exposure.
